CVE-2014-9657 – freetype: off-by-one buffer over-read in tt_face_load_hdmx()
https://notcve.org/view.php?id=CVE-2014-9657
The tt_face_load_hdmx function in truetype/ttpload.c in FreeType before 2.5.4 does not establish a minimum record size, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font. La función tt_face_load_hdmx en truetype/ttpload.c en FreeType anterior a 2.5.4 no establece un tamaño de registro mínimo, lo que permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango) o posiblemente tener otro impacto no especificado a través de una fuente TrueType manipulada. • http://advisories.mageia.org/MGASA-2015-0083.html http://code.google.com/p/google-security-research/issues/detail?id=195 http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=eca0f067068020870a429fe91f6329e499390d55 http://lists.fedoraproject.org/pipermail/package-announce/2015-February/150148.html http://lists.fedoraproject.org/pipermail/package-announce/2015-February/150162.html http://lists.opensuse.org/opensuse-updates/2015-03/msg00091.html http://rhn.redhat.com/errata/RHSA-2015-0696.html • CWE-125: Out-of-bounds Read •
CVE-2014-9664 – freetype: off-by-one buffer over-read in parse_charstrings() / t42_parse_charstrings()
https://notcve.org/view.php?id=CVE-2014-9664
FreeType before 2.5.4 does not check for the end of the data during certain parsing actions, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted Type42 font, related to type42/t42parse.c and type1/t1load.c. FreeType anterior a 2.5.4 no comprueba si hay un final de los datos durante ciertas acciones de análisis sintáctico, lo que permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango) o posiblemente tener otro impacto no especificado a través de una fuente Type42 manipulada, relacionado con type42/t42parse.c y type1/t1load.c. • http://advisories.mageia.org/MGASA-2015-0083.html http://code.google.com/p/google-security-research/issues/detail?id=183 http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=73be9f9ab67842cfbec36ee99e8d2301434c84ca http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=dd89710f0f643eb0f99a3830e0712d26c7642acd http://lists.fedoraproject.org/pipermail/package-announce/2015-February/150148.html http://lists.fedoraproject.org/pipermail/package-announce/2015-February/150162.html http://lists.opensuse& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2014-9668
The woff_open_font function in sfnt/sfobjs.c in FreeType before 2.5.4 proceeds with offset+length calculations without restricting length values, which allows remote attackers to cause a denial of service (integer overflow and heap-based buffer overflow) or possibly have unspecified other impact via a crafted Web Open Font Format (WOFF) file. La función woff_open_font en sfnt/sfobjs.c en FreeType anterior a 2.5.4 proceda con los cálculos de desplazamiento más longitud (offset+length) sin restringir los valores de longitud, lo que permite a atacantes remotos causar una denegación de servicio (desbordamiento de enteros y desbordamiento de buffer basado en memoria dinámica) o posiblemente tener otro impacto no especificado a través de un fichero Web Open Font Format (WOFF) manipulado. • http://code.google.com/p/google-security-research/issues/detail?id=164 http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=f46add13895337ece929b18bb8f036431b3fb538 http://lists.fedoraproject.org/pipermail/package-announce/2015-February/150148.html http://lists.fedoraproject.org/pipermail/package-announce/2015-February/150162.html http://lists.opensuse.org/opensuse-updates/2015-03/msg00091.html http://www.securityfocus.com/bid/72986 http://www.ubuntu.com/usn/USN-2510-1 http://www.ubunt • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2014-9671 – freetype: integer overflow in pcf_get_properties() leading to NULL pointer dereference
https://notcve.org/view.php?id=CVE-2014-9671
Off-by-one error in the pcf_get_properties function in pcf/pcfread.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted PCF file with a 0xffffffff size value that is improperly incremented. Error de superación de límite (off-by-one) en la función pcf_get_properties en pcf/pcfread.c en FreeType anterior a 2.5.4 permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída de aplicación) a través de un fichero PCF manipulado con un valor de tamaño 0xffffffff que está incrementado incorrectamente. • http://advisories.mageia.org/MGASA-2015-0083.html http://code.google.com/p/google-security-research/issues/detail?id=157 http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=0e2f5d518c60e2978f26400d110eff178fa7e3c3 http://lists.opensuse.org/opensuse-updates/2015-03/msg00091.html http://rhn.redhat.com/errata/RHSA-2015-0696.html http://www.debian.org/security/2015/dsa-3188 http://www.mandriva.com/security/advisories?name=MDVSA-2015:055 http://www.oracle.com/technetwork/topics/ • CWE-476: NULL Pointer Dereference •
CVE-2014-9674 – freetype: multiple integer overflows Mac_Read_POST_Resource() leading to heap-based buffer overflows
https://notcve.org/view.php?id=CVE-2014-9674
The Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.5.4 proceeds with adding to length values without validating the original values, which allows remote attackers to cause a denial of service (integer overflow and heap-based buffer overflow) or possibly have unspecified other impact via a crafted Mac font. La función Mac_Read_POST_Resource en base/ftobjs.c en FreeType anterior a 2.5.4 proceda con la suma de los valores de longitud sin validar los valores originales, lo que permite a atacantes remotos causar una denegación de servicio (desbordamiento de enteros y desbordamiento de buffer basado en memoria dinámica) o posiblemente tener otro impacto no especificado a través de una fuente Mac manipulada. Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way FreeType handled Mac fonts. If a specially crafted font file was loaded by an application linked against FreeType, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. • http://advisories.mageia.org/MGASA-2015-0083.html http://code.google.com/p/google-security-research/issues/detail?id=153 http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=240c94a185cd8dae7d03059abec8a5662c35ecd3 http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=cd4a5a26e591d01494567df9dec7f72d59551f6e http://lists.fedoraproject.org/pipermail/package-announce/2015-February/150148.html http://lists.fedoraproject.org/pipermail/package-announce/2015-February/150162.html http://lists.opensuse& • CWE-122: Heap-based Buffer Overflow •
