Buffer overflow in the png_set_PLTE function in libpng before 1.0.65, 1.1.x and 1.2.x before 1.2.55, 1.3.x, 1.4.x before 1.4.18, 1.5.x before 1.5.25, and 1.6.x before 1.6.20 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-8126. Desbordamiento de buffer en la función png_set_PLTE en libpng en versiones anteriores a 1.0.65, 1.1.x y 1.2.x en versiones anteriores a 1.2.55, 1.3.x, 1.4.x en versiones anteriores a 1.4.18, 1.5.x en versiones anteriores a 1.5.25 y 1.6.x en versiones anteriores a 1.6.20 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente tener otro impacto no especificado a través de un valor pequeño de profundidad de bits en un IHDR (también conocido como image header) fragmento en una imagen PNG. NOTA: esta vulnerabilidad existe debido a una solución incorrecta para CVE-2015-8126. It was discovered that the png_get_PLTE() and png_set_PLTE() functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. • http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/174905.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/174936.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/175073.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00041.html http://lists.opensuse.org/opensuse-security-an • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

An array-indexing error was discovered in the png_convert_to_rfc1123() function of libpng.

Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image. Múltiples desbordamientos de buffer en las funciones (1) png_set_PLTE y (2) png_get_PLTE en libpng en versiones anteriores a 1.0.64, 1.1.x y 1.2.x en versiones anteriores a 1.2.54, 1.3.x y 1.4.x en versiones anteriores a 1.4.17, 1.5.x en versiones anteriores a 1.5.24 y 1.6.x en versiones anteriores a 1.6.19 permiten a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente tener otro impacto no especificado a través de un valor bit-depth pequeño en un fragmento IHDR (también conocido como image header) en una imagen PNG. It was discovered that the png_get_PLTE() and png_set_PLTE() functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. In case an application tried to use these functions in combination with properly calculated palette sizes, this could lead to a buffer overflow or out-of-bounds reads. An attacker could exploit this to cause a crash or potentially execute arbitrary code by tricking an unsuspecting user into processing a specially crafted PNG image. • http://googlechromereleases.blogspot.com/2016/03/stable-channel-update.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172324.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172620.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172647.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172663.html http://lists.fedoraproject.org/pipermail • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
