Descriptions

Integer overflow in libpng, as used in Google Chrome before 17.0.963.56, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that trigger an integer truncation.

Desbordamiento de entero en libpng, tal como se utiliza en Google Chrome antes de v17.0.963.56, permite a atacantes remotos causar una denegación de servicio o posiblemente tener un impacto no especificado a través de vectores desconocidos que provocan el truncado de enteros.

Nicolas Gregoire and Aki Helin discovered that when processing a malformed embedded XSLT stylesheet, Thunderbird can crash due to memory corruption. If the user were tricked into opening a specially crafted page, an attacker could exploit this to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Thunderbird. It was discovered that memory corruption could occur during the decoding of Ogg Vorbis files. If the user were tricked into opening a specially crafted file, an attacker could exploit this to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Thunderbird. Various other issues were also addressed.
