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.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0018-1 advisory.

    - CVE-2025-14512: integer overflow in the GIO `escape_byte_string()` function when processing malicious     files or remote       filesystem attribute values can lead to denial-of-service (bsc#1254878).
    - CVE-2025-14087: buffer underflow in the GVariant parser `bytestring_parse()` and     `string_parse()`functions when       processing attacker-influenced data may lead to crash or code execution (bsc#1254662).
    - CVE-2025-13601: heap-based buffer overflow in the `g_escape_uri_string()` function when processing     strings with a       large number of unacceptable characters may lead to crash or code execution (bsc#1254297).

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0970 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-14512:
    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-2025-14087:
    A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap     corruption, leading to a denial of service or potential code execution via a buffer-underflow in the     GVariant parser when processing maliciously crafted input strings.

    Multiple issues were found in GLib, a general-purpose, portable utility     library, that could lead to denial of service, memory corruption or     potentially arbitrary code execution if maliciously crafted data is     processed.

    For Debian 11 bullseye, these problems have been fixed in version     2.66.8-1+deb11u7.

    We recommend that you upgrade your glib2.0 packages.

    For the detailed security status of glib2.0 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/glib2.0
