"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0209 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2021-44648:
    GNOME gdk-pixbuf 2.42.6 is vulnerable to a heap-buffer overflow vulnerability when decoding the lzw
    compressed stream of image data in GIF files with lzw minimum code size equals to 12.

    CVE-2021-46829:
    GNOME GdkPixbuf (aka GDK-PixBuf) before 2.42.8 allows a heap-based buffer overflow when compositing or
    clearing frames in GIF files, as demonstrated by io-gif-animation.c composite_frame. This overflow is
    controllable and could be abused for code execution, especially on 32-bit systems.

    CVE-2022-48622:
    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.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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