CVE-2020-10711 5 Canonical, Debian, Linux and 2 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2023-11-07 4.3 MEDIUM 5.9 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.
CVE-2020-10696 2 Buildah Project, Redhat 3 Buildah, Enterprise Linux, Openshift Container Platform 2023-11-07 9.3 HIGH 8.8 HIGH
A path traversal flaw was found in Buildah in versions before 1.14.5. This flaw allows an attacker to trick a user into building a malicious container image hosted on an HTTP(s) server and then write files to the user's system anywhere that the user has permissions.
CVE-2020-10693 4 Ibm, Oracle, Quarkus and 1 more 8 Websphere Application Server, Weblogic Server, Quarkus and 5 more 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
A flaw was found in Hibernate Validator version 6.1.2.Final. A bug in the message interpolation processor enables invalid EL expressions to be evaluated as if they were valid. This flaw allows attackers to bypass input sanitation (escaping, stripping) controls that developers may have put in place when handling user-controlled data in error messages.
CVE-2020-10690 6 Canonical, Debian, Linux and 3 more 33 Ubuntu Linux, Debian Linux, Linux Kernel and 30 more 2023-11-07 4.4 MEDIUM 6.4 MEDIUM
There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode.
CVE-2020-10687 1 Redhat 4 Enterprise Linux, Jboss Enterprise Application Platform, Single Sign-on and 1 more 2023-11-07 5.8 MEDIUM 4.8 MEDIUM
A flaw was discovered in all versions of Undertow before Undertow 2.2.0.Final, where HTTP request smuggling related to CVE-2017-2666 is possible against HTTP/1.x and HTTP/2 due to permitting invalid characters in an HTTP request. This flaw allows an attacker to poison a web-cache, perform an XSS attack, or obtain sensitive information from request other than their own.
CVE-2019-9959 4 Debian, Fedoraproject, Freedesktop and 1 more 7 Debian Linux, Fedora, Poppler and 4 more 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
The JPXStream::init function in Poppler 0.78.0 and earlier doesn't check for negative values of stream length, leading to an Integer Overflow, thereby making it possible to allocate a large memory chunk on the heap, with a size controlled by an attacker, as demonstrated by pdftocairo.
CVE-2019-9903 5 Canonical, Debian, Fedoraproject and 2 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
PDFDoc::markObject in PDFDoc.cc in Poppler 0.74.0 mishandles dict marking, leading to stack consumption in the function Dict::find() located at Dict.cc, which can (for example) be triggered by passing a crafted pdf file to the pdfunite binary.
CVE-2019-9854 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various script events such as mouse-over, document-open etc. Access is intended to be restricted to scripts under the share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice install. Protection was added, to address CVE-2019-9852, to avoid a directory traversal attack where scripts in arbitrary locations on the file system could be executed by employing a URL encoding attack to defeat the path verification step. However this protection could be bypassed by taking advantage of a flaw in how LibreOffice assembled the final script URL location directly from components of the passed in path as opposed to solely from the sanitized output of the path verification step. This issue affects: Document Foundation LibreOffice 6.2 versions prior to 6.2.7; 6.3 versions prior to 6.3.1.
CVE-2019-9741 4 Debian, Fedoraproject, Golang and 1 more 5 Debian Linux, Fedora, Go and 2 more 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
An issue was discovered in net/http in Go 1.11.5. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the second argument to http.NewRequest with \r\n followed by an HTTP header or a Redis command.
CVE-2019-9636 7 Canonical, Debian, Fedoraproject and 4 more 16 Ubuntu Linux, Debian Linux, Fedora and 13 more 2023-11-07 5.0 MEDIUM 9.8 CRITICAL
Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9.
CVE-2019-9518 11 Apache, Apple, Canonical and 8 more 20 Traffic Server, Mac Os X, Swiftnio and 17 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
CVE-2019-9517 12 Apache, Apple, Canonical and 9 more 25 Http Server, Traffic Server, Mac Os X and 22 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.
CVE-2019-9516 12 Apache, Apple, Canonical and 9 more 21 Traffic Server, Mac Os X, Swiftnio and 18 more 2023-11-07 6.8 MEDIUM 6.5 MEDIUM
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.
CVE-2019-9515 12 Apache, Apple, Canonical and 9 more 24 Traffic Server, Mac Os X, Swiftnio and 21 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-9514 13 Apache, Apple, Canonical and 10 more 30 Traffic Server, Mac Os X, Swiftnio and 27 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
CVE-2019-9513 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.
CVE-2019-9511 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2023-11-07 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-7310 5 Canonical, Debian, Fedoraproject and 2 more 11 Ubuntu Linux, Debian Linux, Fedora and 8 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo.
CVE-2019-7222 7 Canonical, Debian, Fedoraproject and 4 more 18 Ubuntu Linux, Debian Linux, Fedora and 15 more 2023-11-07 2.1 LOW 5.5 MEDIUM
The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak.
CVE-2019-7221 7 Canonical, Debian, Fedoraproject and 4 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2023-11-07 4.6 MEDIUM 7.8 HIGH
The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free.
