insufficient TLB flush for x86 PV guests in shadow mode For migration as well as to work around kernels unaware of L1TF (see XSA-273), PV guests may be run in shadow paging mode. To address XSA-401, code was moved inside a function in Xen. This code movement missed a variable changing meaning / value between old and new code positions. The now wrong use of the variable did lead to a wrong TLB flush condition, omitting flushes where such are necessary.

LibreOffice supports the storage of passwords for web connections in the user’s configuration database. The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice existed where the required initialization vector for encryption was always the same which weakens the security of the encryption making them vulnerable if an attacker has access to the user's configuration data. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions prior to 7.3.1.

LibreOffice supports the storage of passwords for web connections in the user’s configuration database. The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice existed where master key was poorly encoded resulting in weakening its entropy from 128 to 43 bits making the stored passwords vulerable to a brute force attack if an attacker has access to the users stored config. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions prior to 7.3.3.

GNOME GdkPixbuf (aka GDK-PixBuf) before 2.42.8 allows a heap-based buffer overflow when compositing or clearing frames in GIF files, as demonstrated by io-gif-animation.c composite_frame. This overflow is controllable and could be abused for code execution, especially on 32-bit systems.

TZInfo is a Ruby library that provides access to time zone data and allows times to be converted using time zone rules. Versions prior to 0.36.1, as well as those prior to 1.2.10 when used with the Ruby data source tzinfo-data, are vulnerable to relative path traversal. With the Ruby data source, time zones are defined in Ruby files. There is one file per time zone. Time zone files are loaded with `require` on demand. In the affected versions, `TZInfo::Timezone.get` fails to validate time zone identifiers correctly, allowing a new line character within the identifier. With Ruby version 1.9.3 and later, `TZInfo::Timezone.get` can be made to load unintended files with `require`, executing them within the Ruby process. Versions 0.3.61 and 1.2.10 include fixes to correctly validate time zone identifiers. Versions 2.0.0 and later are not vulnerable. Version 0.3.61 can still load arbitrary files from the Ruby load path if their name follows the rules for a valid time zone identifier and the file has a prefix of `tzinfo/definition` within a directory in the load path. Applications should ensure that untrusted files are not placed in a directory on the load path. As a workaround, the time zone identifier can be validated before passing to `TZInfo::Timezone.get` by ensuring it matches the regular expression `\A[A-Za-z0-9+\-_]+(?:\/[A-Za-z0-9+\-_]+)*\z`.

jQuery UI is a curated set of user interface interactions, effects, widgets, and themes built on top of jQuery. Versions prior to 1.13.2 are potentially vulnerable to cross-site scripting. Initializing a checkboxradio widget on an input enclosed within a label makes that parent label contents considered as the input label. Calling `.checkboxradio( "refresh" )` on such a widget and the initial HTML contained encoded HTML entities will make them erroneously get decoded. This can lead to potentially executing JavaScript code. The bug has been patched in jQuery UI 1.13.2. To remediate the issue, someone who can change the initial HTML can wrap all the non-input contents of the `label` in a `span`.

In libtirpc before 1.3.3rc1, remote attackers could exhaust the file descriptors of a process that uses libtirpc because idle TCP connections are mishandled. This can, in turn, lead to an svc_run infinite loop without accepting new connections.

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 17.0.3.1; Oracle GraalVM Enterprise Edition: 21.3.2 and 22.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, 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 3.1 Base Score 5.3 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).
