ALSA-2023:6631 — Low: glib2 security and bug fix update

Affected: AlmaLinux:9: glib2, AlmaLinux:9: glib2-devel, AlmaLinux:9: glib2-doc, AlmaLinux:9: glib2-static, AlmaLinux:9: glib2-tests

GLib provides the core application building blocks for libraries and applications written in C. It provides the core object system used in GNOME, the main loop implementation, and a large set of utility functions for strings and common data structures.

Security Fix(es):

* glib: GVariant offset table entry size is not checked in is_normal() (CVE-2023-29499) * glib: g_variant_byteswap() can take a long time with some non-normal inputs (CVE-2023-32611) * glib: GVariant deserialisation does not match spec for non-normal data (CVE-2023-32665)

ICSA-23-348-10 — Siemens SIMATIC S7-1500

expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE. shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees run-mailcap in the Debian mime-support package before 3.52-1+deb7u1 allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a filename. In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9 Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start o…
