CVE-2020-5973 2 Canonical, Nvidia 2 Ubuntu Linux, Virtual Gpu 2021-07-21 2.1 LOW 4.4 MEDIUM
NVIDIA Virtual GPU Manager and the guest drivers contain a vulnerability in vGPU plugin, in which there is the potential to execute privileged operations, which may lead to denial of service. This affects vGPU version 8.x (prior to 8.4), version 9.x (prior to 9.4) and version 10.x (prior to 10.3).
CVE-2019-7306 2 Byobu, Canonical 2 Byobu, Ubuntu Linux 2021-07-21 5.0 MEDIUM 7.5 HIGH
Byobu Apport hook may disclose sensitive information since it automatically uploads the local user's .screenrc which may contain private hostnames, usernames and passwords. This issue affects: byobu
CVE-2019-20908 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2021-07-21 6.9 MEDIUM 6.7 MEDIUM
An issue was discovered in drivers/firmware/efi/efi.c in the Linux kernel before 5.4. Incorrect access permissions for the efivar_ssdt ACPI variable could be used by attackers to bypass lockdown or secure boot restrictions, aka CID-1957a85b0032.
CVE-2019-14615 2 Canonical, Intel 709 Ubuntu Linux, Atom E3805, Atom E3805 Firmware and 706 more 2021-07-21 1.9 LOW 5.5 MEDIUM
Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may allow an unauthenticated user to potentially enable information disclosure via local access.
CVE-2019-11815 5 Canonical, Debian, Linux and 2 more 15 Ubuntu Linux, Debian Linux, Linux Kernel and 12 more 2021-07-21 9.3 HIGH 8.1 HIGH
An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel before 5.0.8. There is a race condition leading to a use-after-free, related to net namespace cleanup.
CVE-2019-15031 4 Canonical, Linux, Opensuse and 1 more 4 Ubuntu Linux, Linux Kernel, Leap and 1 more 2021-07-21 3.6 LOW 4.4 MEDIUM
In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c.
CVE-2019-17542 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2021-07-21 7.5 HIGH 9.8 CRITICAL
FFmpeg before 4.2 has a heap-based buffer overflow in vqa_decode_chunk because of an out-of-array access in vqa_decode_init in libavcodec/vqavideo.c.
CVE-2019-12521 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2021-07-21 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing.
CVE-2020-5963 2 Canonical, Nvidia 9 Ubuntu Linux, Geforce, Geforce Firmware and 6 more 2021-07-21 4.6 MEDIUM 7.8 HIGH
NVIDIA Windows GPU Display Driver, all versions, contains a vulnerability in the Inter Process Communication APIs, in which improper access control may lead to code execution, denial of service, or information disclosure.
CVE-2020-8517 3 Canonical, Opensuse, Squid-cache 3 Ubuntu Linux, Leap, Squid 2021-07-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer. On systems with memory access protections, this can result in the helper process being terminated unexpectedly. This leads to the Squid process also terminating and a denial of service for all clients using the proxy.
CVE-2019-13627 4 Canonical, Debian, Libgcrypt20 Project and 1 more 4 Ubuntu Linux, Debian Linux, Libgcrypt20 and 1 more 2021-07-21 2.6 LOW 6.3 MEDIUM
It was discovered that there was a ECDSA timing attack in the libgcrypt20 cryptographic library. Version affected: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Versions fixed: 1.8.5-2 and 1.6.3-2+deb8u7.
CVE-2020-6831 4 Canonical, Debian, Mozilla and 1 more 6 Ubuntu Linux, Debian Linux, Firefox and 3 more 2021-07-21 7.5 HIGH 9.8 CRITICAL
A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
CVE-2020-2583 7 Canonical, Debian, Mcafee and 4 more 24 Ubuntu Linux, Debian Linux, Epolicy Orchestrator and 21 more 2021-07-21 4.3 MEDIUM 3.7 LOW
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Serialization). Supported versions that are affected are Java SE: 7u241, 8u231, 11.0.5 and 13.0.1; Java SE Embedded: 8u231. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.0 Base Score 3.7 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).
CVE-2018-7183 4 Canonical, Freebsd, Netapp and 1 more 4 Ubuntu Linux, Freebsd, Element Software and 1 more 2021-07-20 7.5 HIGH 9.8 CRITICAL
Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6 through 4.2.8p10 allows remote attackers to execute arbitrary code by leveraging an ntpq query and sending a response with a crafted array.
CVE-2013-7449 3 Canonical, Hexchat Project, Xchat 4 Ubuntu Linux, Hexchat, Xchat and 1 more 2021-07-20 5.8 MEDIUM 6.5 MEDIUM
The ssl_do_connect function in common/server.c in HexChat before 2.10.2, XChat, and XChat-GNOME does not verify that the server hostname matches a domain name in the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
CVE-2020-12826 3 Canonical, Linux, Redhat 4 Ubuntu Linux, Linux Kernel, Enterprise Linux and 1 more 2021-07-15 4.4 MEDIUM 5.3 MEDIUM
A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2. Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat.
CVE-2018-15120 2 Canonical, Gnome 2 Ubuntu Linux, Pango 2021-07-14 4.3 MEDIUM 6.5 MEDIUM
libpango in Pango 1.40.8 through 1.42.3, as used in hexchat and other products, allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted text with invalid Unicode sequences.
CVE-2011-3193 5 Canonical, Gnome, Opensuse and 2 more 8 Ubuntu Linux, Pango, Opensuse and 5 more 2021-07-14 9.3 HIGH N/A
Heap-based buffer overflow in the Lookup_MarkMarkPos function in the HarfBuzz module (harfbuzz-gpos.c), as used by Qt before 4.7.4 and Pango, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted font file.
CVE-2019-19069 4 Broadcom, Canonical, Linux and 1 more 21 Fabric Operating System, Ubuntu Linux, Linux Kernel and 18 more 2021-06-22 7.8 HIGH 7.5 HIGH
A memory leak in the fastrpc_dma_buf_attach() function in drivers/misc/fastrpc.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering dma_get_sgtable() failures, aka CID-fc739a058d99.
CVE-2014-0190 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Opensuse and 1 more 2021-06-16 4.3 MEDIUM N/A
The GIF decoder in QtGui in Qt before 5.3 allows remote attackers to cause a denial of service (NULL pointer dereference) via invalid width and height values in a GIF image.
