The png_handle_sCAL function in pngrutil.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 does not properly handle invalid sCAL chunks, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted PNG image that triggers the reading of uninitialized memory. La función png_handle_sCAL de pngrutil.c en libpng v1.0.x antes de la v1.0.55, en v1.2.x antes de la v1.2.45, en v1.4.x antes de la v1.4.8, y en v1.5.x antes de la v1.5.4, no controla correctamente fragmentos inválidos SCAL, que permiten a atacantes remotos causar una denegación de servicio (corrupción de memoria y caída de aplicación) o posiblemente tener un impacto no especificado a través de una imagen PNG creada que provoca la lectura de la memoria sin inicializar. • http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng/libpng%3Ba=commit%3Bh=61a2d8a2a7b03023e63eae9a3e64607aaaa6d339 http://lists.apple.com/archives/Security-announce/2011//Oct/msg00003.html http://lists.apple.com/archives/security-announce/2012/May/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/063118.html http://secunia.com/advisories/45046 http://secunia.com/advisories/45405 http://secunia.com/advisories/45415 http://secunia.com/advisories/45445 http://secun • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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.

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 •

libpng before 1.2.37 does not properly parse 1-bit interlaced images with width values that are not divisible by 8, which causes libpng to include uninitialized bits in certain rows of a PNG file and might allow remote attackers to read portions of sensitive memory via "out-of-bounds pixels" in the file. libpng anteriores a v1.2.37 no parsea adecuadamente 1-bit de imágenes entrelazadas con valores de ancho que no son divisibles por 8, lo que produce que libpng incluya bits sin inicializar en ciertas filas del fichero PNG lo que permitiría atacantes remotos leer trozos de memoria sensible a través de "pixeles fuera de rango" en el fichero. • http://archives.neohapsis.com/archives/bugtraq/2010-04/0077.html http://archives.neohapsis.com/archives/fulldisclosure/2010-04/0121.html http://lists.apple.com/archives/security-announce/2010//Mar/msg00001.html http://lists.vmware.com/pipermail/security-announce/2010/000090.html http://secunia.com/advisories/35346 http://secunia.com/advisories/35470 http://secunia.com/advisories/35524 http://secunia.com/advisories/35594 http://secunia.com/advisories/39206 http://secunia.com/advisories&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
