CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 3CVE-2021-46829 – gdk-pixbuf: heap-based buffer overflow when compositing or clearing frames in GIF files
https://notcve.org/view.php?id=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. GdkPixbuf de GNOME (también se conoce como GDK-PixBuf) versiones anteriores a 2.42.8, permite un desbordamiento del búfer en la región heap de la memoria cuando son compuestos o borran fotogramas en archivos GIF, como es demostrado por el archivo io-gif-animation.c composite_frame. Este desbordamiento es controlable y podría ser abusado para la ejecución de código, especialmente en sistemas de 32 bits A heap-based buffer overflow vulnerability was found in GNOME GdkPixbuf (aka GDK-PixBuf) when compositing or clearing frames in GIF files. The vulnerability exists due to a boundary error when processing GIF images. • http://www.openwall.com/lists/oss-security/2022/07/25/1 https://github.com/pedrib/PoC/blob/master/fuzzing/CVE-2021-46829/CVE-2021-46829.md https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/commit/5398f04d772f7f8baf5265715696ed88db0f0512 https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/commit/bca00032ad68d0b0aa2c1f7558db931e52bd9cd2 https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/issues/190 https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/merge_requests/121 https://lists.fedoraproject.org/archives/list/ • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

A flaw was found in gdk-pixbuf in versions before 2.42.0. An integer wraparound leading to an out of bounds write can occur when a crafted GIF image is loaded. An attacker may cause applications to crash or could potentially execute code on the victim system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo en gdk-pixbuf en versiones anteriores a 2.42.0. • https://bugzilla.redhat.com/show_bug.cgi?id=1926787 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/B5H3GNVWMZTYZR3JBYCK57PF7PFMQBNP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BGZVCTH5O7WBJLYXZ2UOKLYNIFPVR55D https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EANWYODLOJDFLMBH6WEKJJMQ5PKLEWML • CWE-191: Integer Underflow (Wrap or Wraparound) •

GNOME gdk-pixbuf (aka GdkPixbuf) before 2.42.2 allows a denial of service (infinite loop) in lzw.c in the function write_indexes. if c->self_code equals 10, self->code_table[10].extends will assign the value 11 to c. The next execution in the loop will assign self->code_table[11].extends to c, which will give the value of 10. This will make the loop run infinitely. This bug can, for example, be triggered by calling this function with a GIF image with LZW compression that is crafted in a special way. GNOME gdk-pixbuf (también se conoce como GdkPixbuf) versiones anteriores a 2.42.2, permite una denegación de servicio (bucle infinito) en el archivo lzw.c en la función write_indexes. • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977166 https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/blob/master/NEWS https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/issues/164 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/B5H3GNVWMZTYZR3JBYCK57PF7PFMQBNP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BGZVCTH5O7WBJLYXZ2UOKLYNIFPVR55D https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

An exploitable integer overflow vulnerability exists in the tiff_image_parse functionality of Gdk-Pixbuf 2.36.6 when compiled with Clang. A specially crafted tiff file can cause a heap-overflow resulting in remote code execution. An attacker can send a file or a URL to trigger this vulnerability. Existe una vulnerabilidad explotable de desbordamiento de enteros en la funcionalidad tiff_image_parse de Gdk-Pixbuf 2.36.6 cuando se compila con Clang. Un archivo tiff especialmente manipulado puede provocar un desbordamiento de montículos que daría lugar a la ejecución remota de código. • http://www.securityfocus.com/bid/100541 https://lists.debian.org/debian-lts-announce/2019/12/msg00025.html https://www.talosintelligence.com/vulnerability_reports/TALOS-2017-0377 • CWE-190: Integer Overflow or Wraparound •
