AlmaLinux 9.2 [TuxCare] Security Update: glib2 / glib2-devel / glib2-doc / glib2-static / glib2-tests Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2026:1776329620)

medium Nessus Plugin ID 360815

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1776329620 advisory.

- A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing malicious file or remote filesystem attribute values. (CVE-2025-14512)

- A flaw was found in glib. An integer overflow during temporary file creation leads to an out-of-bounds memory access, allowing an attacker to potentially perform path traversal or access private temporary file content by creating symbolic links. This vulnerability allows a local attacker to manipulate file paths and access unauthorized data. The core issue stems from insufficient validation of file path lengths during temporary file operations. (CVE-2025-7039)

- A flaw was found in glib. Missing validation of offset and count parameters in the g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When specially crafted values are provided, this overflow results in an incorrect size being passed to memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service (DoS). (CVE-2026-0988)

- A flaw was found in the GLib Base64 encoding routine when processing very large input data. Due to incorrect use of integer types during length calculation, the library may miscalculate buffer boundaries.
This can cause memory writes outside the allocated buffer. Applications that process untrusted or extremely large Base64 input using GLib may crash or behave unpredictably. (CVE-2026-1484)

- A flaw was found in Glib's content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability. (CVE-2026-1485)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2026:1776329620.
