Amazon Linux 2 : gdk-pixbuf2 (ALAS-2025-2948)

high Nessus Plugin ID 243430

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of gdk-pixbuf2 installed on the remote host is prior to 2.36.12-3. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2948 advisory.

In GNOME GdkPixbuf (aka gdk-pixbuf) through 2.42.10, the ANI (Windows animated cursor) decoder encounters heap memory corruption (in ani_load_chunk in io-ani.c) when parsing chunks in a crafted .ani file. A crafted file could allow an attacker to overwrite heap metadata, leading to a denial of service or code execution attack. This occurs in gdk_pixbuf_set_option() in gdk-pixbuf.c. (CVE-2022-48622)

A flaw exists in gdk-pixbuf within the gdk_pixbuf__jpeg_image_load_increment function (io-jpeg.c) and in glib's g_base64_encode_step (glib/gbase64.c). When processing maliciously crafted JPEG images, a heap buffer overflow can occur during Base64 encoding, allowing out-of-bounds reads from heap memory, potentially causing application crashes or arbitrary code execution. (CVE-2025-7345)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update gdk-pixbuf2' to update your system.
