CVE-2025-6199

Gdk-pixbuf: uninitialized memory disclosure in gdkpixbuf gif lzw decoder

A flaw was found in the GIF parser of GdkPixbuf’s LZW decoder. When an invalid symbol is encountered during decompression, the decoder sets the reported output size to the full buffer length rather than the actual number of written bytes. This logic error results in uninitialized sections of the buffer being included in the output, potentially leaking arbitrary memory contents in the processed image.

CVE-2004-0753

security flaw

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.

CVE-2004-0782

security flaw

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).

CVE-2004-0783

security flaw

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).

CVE-2005-2976

security flaw

Integer overflow in io-xpm.c in gdk-pixbuf 0.22.0 in GTK+ before 2.8.7 allows attackers to cause a denial of service (crash) or execute arbitrary code via an XPM file with large height, width, and colour values, a different vulnerability than CVE-2005-3186.

CVE-2005-3186

security flaw

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.

CVE-2022-48622

gnome: heap memory corruption on gdk-pixbuf

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.
