Security update for glib2
This update for glib2 fixes the following issues:
- CVE-2026-1485: Fixed buffer underflow and out-of-bounds access due to integer wraparound in content type parsing (bsc#1257354).
- CVE-2026-1484: Fixed buffer underflow and out-of-bounds access due to miscalculated buffer boundaries in the Base64 encoding routine (bsc#1257355).
- CVE-2026-1489: Fixed undersized heap allocation followed by out-of-bounds access due to integer overflow in Unicode case conversion (bsc#1257353).

Описание
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.

Описание
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.

Описание
A flaw was found in GLib. An integer overflow vulnerability in its Unicode case conversion implementation can lead to memory corruption. By processing specially crafted and extremely large Unicode strings, an attacker could trigger an undersized memory allocation, resulting in out-of-bounds writes. This could cause applications utilizing GLib for string conversion to crash or become unstable.
