| CVE-2022-34918 | 4 Canonical, Debian, Linux and 1 more | 13 Ubuntu Linux, Debian Linux, Linux Kernel and 10 more | 2023-11-07 | 7.2 HIGH | 7.8 HIGH |
| An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. | |||||
| CVE-2021-4120 | 2 Canonical, Fedoraproject | 3 Snapd, Ubuntu Linux, Fedora | 2023-11-07 | 4.6 MEDIUM | 7.8 HIGH |
| snapd 2.54.2 fails to perform sufficient validation of snap content interface and layout paths, resulting in the ability for snaps to inject arbitrary AppArmor policy rules via malformed content interface and layout declarations and hence escape strict snap confinement. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 | |||||
| CVE-2021-4115 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2023-11-07 | 2.1 LOW | 5.5 MEDIUM |
| There is a flaw in polkit which can allow an unprivileged user to cause polkit to crash, due to process file descriptor exhaustion. The highest threat from this vulnerability is to availability. NOTE: Polkit process outage duration is tied to the failing process being reaped and a new one being spawned | |||||
| CVE-2021-4093 | 4 Canonical, Fedoraproject, Linux and 1 more | 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more | 2023-11-07 | 7.2 HIGH | 8.8 HIGH |
| A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example, outs or ins) using the exit reason SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape scenario. | |||||
| CVE-2021-4034 | 7 Canonical, Oracle, Polkit Project and 4 more | 32 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 29 more | 2023-11-07 | 7.2 HIGH | 7.8 HIGH |
| A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. | |||||
| CVE-2021-45079 | 4 Canonical, Debian, Fedoraproject and 1 more | 5 Ubuntu Linux, Debian Linux, Extra Packages For Enterprise Linux and 2 more | 2023-11-07 | 5.8 MEDIUM | 9.1 CRITICAL |
| In strongSwan before 5.9.5, a malicious responder can send an EAP-Success message too early without actually authenticating the client and (in the case of EAP methods with mutual authentication and EAP-only authentication for IKEv2) even without server authentication. | |||||
| CVE-2021-44731 | 3 Canonical, Debian, Fedoraproject | 4 Snapd, Ubuntu Linux, Debian Linux and 1 more | 2023-11-07 | 6.9 MEDIUM | 7.8 HIGH |
| A race condition existed in the snapd 2.54.2 snap-confine binary when preparing a private mount namespace for a snap. This could allow a local attacker to gain root privileges by bind-mounting their own contents inside the snap's private mount namespace and causing snap-confine to execute arbitrary code and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 | |||||
| CVE-2021-44730 | 3 Canonical, Debian, Fedoraproject | 4 Snapd, Ubuntu Linux, Debian Linux and 1 more | 2023-11-07 | 6.9 MEDIUM | 8.8 HIGH |
| snapd 2.54.2 did not properly validate the location of the snap-confine binary. A local attacker who can hardlink this binary to another location to cause snap-confine to execute other arbitrary binaries and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 | |||||
| CVE-2021-44420 | 5 Canonical, Debian, Djangoproject and 2 more | 5 Ubuntu Linux, Debian Linux, Django and 2 more | 2023-11-07 | 7.5 HIGH | 7.3 HIGH |
| In Django 2.2 before 2.2.25, 3.1 before 3.1.14, and 3.2 before 3.2.10, HTTP requests for URLs with trailing newlines could bypass upstream access control based on URL paths. | |||||
| CVE-2021-44142 | 6 Canonical, Debian, Fedoraproject and 3 more | 23 Ubuntu Linux, Debian Linux, Fedora and 20 more | 2023-11-07 | 9.0 HIGH | 8.8 HIGH |
| The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. | |||||
| CVE-2021-3737 | 6 Canonical, Fedoraproject, Netapp and 3 more | 17 Ubuntu Linux, Fedora, Hci and 14 more | 2023-11-07 | 7.1 HIGH | 7.5 HIGH |
| A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2021-3640 | 5 Canonical, Debian, Fedoraproject and 2 more | 20 Ubuntu Linux, Debian Linux, Fedora and 17 more | 2023-11-07 | 6.9 MEDIUM | 7.0 HIGH |
| A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system. | |||||
| CVE-2021-3560 | 4 Canonical, Debian, Polkit Project and 1 more | 7 Ubuntu Linux, Debian Linux, Polkit and 4 more | 2023-11-07 | 7.2 HIGH | 7.8 HIGH |
| It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-9490 | 7 Apache, Canonical, Debian and 4 more | 25 Http Server, Ubuntu Linux, Debian Linux and 22 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. | |||||
| CVE-2020-9484 | 7 Apache, Canonical, Debian and 4 more | 26 Tomcat, Ubuntu Linux, Debian Linux and 23 more | 2023-11-07 | 4.4 MEDIUM | 7.0 HIGH |
| When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed. | |||||
| CVE-2020-9402 | 5 Canonical, Debian, Djangoproject and 2 more | 5 Ubuntu Linux, Debian Linux, Django and 2 more | 2023-11-07 | 6.5 MEDIUM | 8.8 HIGH |
| Django 1.11 before 1.11.29, 2.2 before 2.2.11, and 3.0 before 3.0.4 allows SQL Injection if untrusted data is used as a tolerance parameter in GIS functions and aggregates on Oracle. By passing a suitably crafted tolerance to GIS functions and aggregates on Oracle, it was possible to break escaping and inject malicious SQL. | |||||
| CVE-2020-9308 | 3 Canonical, Fedoraproject, Libarchive | 3 Ubuntu Linux, Fedora, Libarchive | 2023-11-07 | 6.8 MEDIUM | 8.8 HIGH |
| archive_read_support_format_rar5.c in libarchive before 3.4.2 attempts to unpack a RAR5 file with an invalid or corrupted header (such as a header size of zero), leading to a SIGSEGV or possibly unspecified other impact. | |||||
| CVE-2020-9274 | 4 Canonical, Debian, Fedoraproject and 1 more | 5 Ubuntu Linux, Debian Linux, Extra Packages For Enterprise Linux and 2 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Pure-FTPd 1.0.49. An uninitialized pointer vulnerability has been detected in the diraliases linked list. When the *lookup_alias(const char alias) or print_aliases(void) function is called, they fail to correctly detect the end of the linked list and try to access a non-existent list member. This is related to init_aliases in diraliases.c. | |||||
| CVE-2020-8927 | 6 Canonical, Debian, Fedoraproject and 3 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2023-11-07 | 6.4 MEDIUM | 6.5 MEDIUM |
| A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a "one-shot" decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the "streaming" API as opposed to the "one-shot" API, and impose chunk size limits. | |||||
| CVE-2020-8835 | 4 Canonical, Fedoraproject, Linux and 1 more | 47 Ubuntu Linux, Fedora, Linux Kernel and 44 more | 2023-11-07 | 7.2 HIGH | 7.8 HIGH |
| In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780) | |||||
