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.

io-xpm.c in the gdk-pixbuf XPM image rendering library in GTK+ before 2.8.7 allows attackers to cause a denial of service (infinite loop) via a crafted XPM image with a large number of colors.

Integer overflow in the GTK+ gdk-pixbuf XPM image rendering library in GTK+ 2.4.0 allows attackers to execute arbitrary code via an XPM file with a number of colors that causes insufficient memory to be allocated, which leads to a heap-based buffer overflow.

The BMP image processor for (1) gdk-pixbuf before 0.22 and (2) gtk2 before 2.2.4 allows remote attackers to cause a denial of service (infinite loop) via a crafted BMP file.

Integer overflow in pixbuf_create_from_xpm (io-xpm.c) in the XPM image decoder for gtk+ 2.4.4 (gtk2) and earlier, and gdk-pixbuf before 0.22, allows remote attackers to execute arbitrary code via certain n_col and cpp values that enable a heap-based buffer overflow. NOTE: this identifier is ONLY for gtk+. It was incorrectly referenced in an advisory for a different issue (CVE-2004-0687).

Stack-based buffer overflow in xpm_extract_color (io-xpm.c) in the XPM image decoder for gtk+ 2.4.4 (gtk2) and earlier, and gdk-pixbuf before 0.22, may allow remote attackers to execute arbitrary code via a certain color string. NOTE: this identifier is ONLY for gtk+. It was incorrectly referenced in an advisory for a different issue (CVE-2004-0688).

Integer overflow in the ICO image decoder for (1) gdk-pixbuf before 0.22 and (2) gtk2 before 2.2.4 allows remote attackers to cause a denial of service (application crash) via a crafted ICO file.

gdk-pixbuf before 0.20 allows attackers to cause a denial of service (crash) via a malformed bitmap (BMP) file.
