"According to the versions of the gdk-pixbuf2 packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :

    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)

Tenable has extracted the preceding description block directly from the EulerOS gdk-pixbuf2 security advisory.

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