Heap-based buffer overflow in tif_ojpeg.c in the OJPEG decoder in LibTIFF before 3.9.5 allows remote attackers to execute arbitrary code via a crafted TIFF file. Desbordamiento de búfer basado en memoria dinámica en tif_ojpeg.c en el decodificador OJPEG en LibTIFF anterior a v3.9.5 permite a atacantes remotos ejecutar código arbitrario mediante un fichero TIFF manipulado. • https://www.exploit-db.com/exploits/22681 http://bugzilla.maptools.org/show_bug.cgi?id=1999 http://lists.fedoraproject.org/pipermail/package-announce/2011-April/058478.html http://openwall.com/lists/oss-security/2011/04/12/10 http://secunia.com/advisories/44271 http://secunia.com/advisories/50726 http://security.gentoo.org/glsa/glsa-201209-02.xml http://securitytracker.com/id?1025380 http://www.debian.org/security/2011/dsa-2256 http://www.mandriva.com/security/advisories? • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Heap-based buffer overflow in the thunder (aka ThunderScan) decoder in tif_thunder.c in LibTIFF 3.9.4 and earlier allows remote attackers to execute arbitrary code via crafted THUNDER_2BITDELTAS data in a .tiff file that has an unexpected BitsPerSample value. Desbordamiento de búfer basado en memoria dinámica en el decodificador Thunder (tambien conocido por ThunderScan) en tif_thunder.c de LibTIFF v3.9.4 y anteriores ,permite a atacantes remotos causar una denegación de servicio (cuelgue) o ejecutar código arbitrario a través de datos manipulados con THUNDER_2BITDELTAS en un fichero .tiff con un valor de BitsPerSample inesperado. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of libtiff. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the implementation of the ThunderDecode codec. While decoding a particular code within a row, the decoder will fail to accommodate for the total expanded size of the row. • http://blackberry.com/btsc/KB27244 http://bugzilla.maptools.org/show_bug.cgi?id=2300 http://lists.apple.com/archives/security-announce/2012/Feb/msg00000.html http://lists.apple.com/archives/security-announce/2012/May/msg00001.html http://lists.apple.com/archives/security-announce/2012/Sep/msg00003.html http://lists.fedoraproject.org/pipermail/package-announce/2011-April/057763.html http://lists.fedoraproject.org/pipermail/package-announce/2011-April/057840.html http://lists.opensuse.org/opensuse& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

LibTIFF before 3.9.2-5.2.1 in SUSE openSUSE 11.3 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a crafted TIFF image. LibTIFF anterior v3.9.2-5.2.1 en SUSE openSUSE v11.3 permite a atacantes remotos causar una denegación de servicio (corrupción de memoria) o probablemente ejecutar código de su elección a través de una imagen TIFF manipulada. • http://blackberry.com/btsc/KB27244 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00006.html http://secunia.com/advisories/50726 http://security.gentoo.org/glsa/glsa-201209-02.xml http://support.novell.com/security/cve/CVE-2010-3087.html https://bugzilla.novell.com/show_bug.cgi?id=624215 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The TIFFExtractData macro in LibTIFF before 3.9.4 does not properly handle unknown tag types in TIFF directory entries, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted TIFF file. La macro TIFFExtractData en LibTIFF anteior v3.9.4 no maneja adecuadamente tipos de etiquetas desconocidas en entradas de directorios TIFF, lo que permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango y caída de programa) a través de ficheros TIFF manipulados. • http://bugzilla.maptools.org/show_bug.cgi?id=2210 http://marc.info/?l=oss-security&m=127731610612908&w=2 http://marc.info/?l=oss-security&m=127736307002102&w=2 http://marc.info/?l=oss-security&m=127738540902757&w=2 http://marc.info/? • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

LibTIFF 3.9.4 and earlier does not properly handle an invalid td_stripbytecount field, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted TIFF file, a different vulnerability than CVE-2010-2443. LibTIFF v3.9.4 y anteriores no manejan adecuadamente el campo invalid td_stripbytecount, lo que pemite a atacantes remotos causar una denegación de servicio (desreferencia de puntero nulo y caída de programa) a través de un fichero TIFF manipulado, una vulnerabilidad diferente que CVE-2010-2443. • https://www.exploit-db.com/exploits/14573 http://bugzilla.maptools.org/show_bug.cgi?id=1996 http://marc.info/?l=oss-security&m=127736307002102&w=2 http://marc.info/?l=oss-security&m=127738540902757&w=2 http://marc.info/?l=oss-security&m=127797353202873&w=2 http://secunia.com/advisories/40422 http://secunia.com/advisories/50726 http://security.gentoo.org/glsa/glsa-201209-02.xml http://www.debian.org/security/2012/dsa-2552 http://www.openwall.com/lists/oss& •
