Heap-based buffer overflow in the png_combine_row function in libpng before 1.5.21 and 1.6.x before 1.6.16, when running on 64-bit systems, might allow context-dependent attackers to execute arbitrary code via a "very wide interlaced" PNG image. Desbordamiento de buffer basado en memoria dinámica en la función png_combine_row en libpng en versiones anteriores a 1.5.21 y 1.6.x en versiones anteriores a 1.6.16, cuando se ejecuta en sistemas de 64 bits, podría permitir a atacantes dependientes del contexto ejecutar código arbitrario a través de una imagen PNG "entrelazada muy ampliamente". • http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://secunia.com/advisories/62725 http://sourceforge.net/p/png-mng/mailman/message/33172831 http://sourceforge.net/p/png-mng/mailman/message/33173461 http://www.openwall.com/lists/oss-security/2015/01/04/3 http://www.openwall.com/lists/oss-security/2015/01/10/1 http://www.openwall.com/lists/oss-security/2015/01/10/3 http://www.oracle.com/technetwork/topics/security/bulletinjul2015-2511963.html h • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The png_push_read_chunk function in pngpread.c in the progressive decoder in libpng 1.6.x through 1.6.9 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via an IDAT chunk with a length of zero. La función png_push_read_chunk en pngpread.c en el decodificador progresivo en libpng 1.6.x hasta 1.6.9 permite a atacantes remotos causar una denegación de servicio (bucle infinito y consumo de CPU) a través de un fragmento IDAT con una longitud cero. • ftp://ftp.simplesystems.org/pub/png/src/libpng16/patch-libpng16-vu684412.diff http://lists.opensuse.org/opensuse-updates/2014-03/msg00029.html http://www.kb.cert.org/vuls/id/684412 https://sourceforge.net/projects/libpng/files/libpng16/patch-libpng16-vu684412.diff • CWE-189: Numeric Errors •

The png_do_expand_palette function in libpng before 1.6.8 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via (1) a PLTE chunk of zero bytes or (2) a NULL palette, related to pngrtran.c and pngset.c. La función png_do_expand_palette en libpng anteriores a 1.6.8 permite a atacantes remotos causar una denegación de servicio (referencia a puntero NULO y crash de la aplicación) a través de (1) un chunk PLTE de cero bytes o (2) una paleta NULL, relacionada con pngrtran.c y pngset.c • http://advisories.mageia.org/MGASA-2014-0075.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127947.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127952.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/128098.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/128099.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/128114.html http://lists.opensuse.org/opensuse-updates/2014-01/m •
