Memory leak in pngrutil.c in libpng before 1.2.44, and 1.4.x before 1.4.3, allows remote attackers to cause a denial of service (memory consumption and application crash) via a PNG image containing malformed Physical Scale (aka sCAL) chunks.

CVSS: 4.3EPSS: 1%CPEs: 21EXPL: 0CVE-2010-0205 – libpng: excessive memory consumption due to highly compressed huge ancillary chunk
https://notcve.org/view.php?id=CVE-2010-0205
The png_decompress_chunk function in pngrutil.c in libpng 1.0.x before 1.0.53, 1.2.x before 1.2.43, and 1.4.x before 1.4.1 does not properly handle compressed ancillary-chunk data that has a disproportionately large uncompressed representation, which allows remote attackers to cause a denial of service (memory and CPU consumption, and application hang) via a crafted PNG file, as demonstrated by use of the deflate compression method on data composed of many occurrences of the same character, related to a "decompression bomb" attack. La función png_decompress_chunk en pngrutil.c en libpng 1.0.x en versiones anteriores a la 1.0.53, 1.2.x en versiones anteriores a la 1.2.43 y1.4.x en versiones anteriores a la 1.4.1 no maneja adecuadamente los datos fragmentados auxiliares comprimidos que tienen una representación descomprimida desproporcionada, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de la CPU y de la memoria y cuelgue de la aplicación) mediante un fichero PNG manipulado, como ha quedado demostrado por el uso del método de decompresión con datos con muchas ocurrencias del mismo caracter, en relación con un ataque "decompression bomb" (bomba de descompresión). • http://libpng.sourceforge.net/ADVISORY-1.4.1.html http://libpng.sourceforge.net/decompression_bombs.html http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-March/037237.html http://lists.fedoraproject.org/pipermail/package-announce/2010-March/037355.html http://lists.fedoraproject.org/pipermail/package-announce/2010-March/037364.html http://lists.fedoraproject.org/pipermail/package-announce/2010-March/037607.html http:/ • CWE-400: Uncontrolled Resource Consumption •
