CVSS: 7.5EPSS: 2%CPEs: 23EXPL: 1CVE-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 •

https://notcve.org/view.php?id=CVE-2014-9670
Multiple integer signedness errors in the pcf_get_encodings function in pcf/pcfread.c in FreeType before 2.5.4 allow remote attackers to cause a denial of service (integer overflow, NULL pointer dereference, and application crash) via a crafted PCF file that specifies negative values for the first column and first row. Múltiples erroes de signo de enteros en la función pcf_get_encodings en pcf/pcfread.c en FreeType anterior a 2.5.4 permiten a atacantes remotos causar una denegación de servicio (desbordamiento de enteros, referencia a puntero nulo y caída de aplicación) a través de un fichero PCF manipulado que especifica valores negativos para la primera columna y la primera fila. • http://advisories.mageia.org/MGASA-2015-0083.html http://code.google.com/p/google-security-research/issues/detail?id=158 http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=ef1eba75187adfac750f326b563fe543dd5ff4e6 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-189: Numeric Errors CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2014-9661
type42/t42parse.c in FreeType before 2.5.4 does not consider that scanning can be incomplete without triggering an error, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted Type42 font. type42/t42parse.c en FreeType anterior a 2.5.4 no considera que escaneo puede resultar incompleto sin provoca un error, lo que permite a atacantes remotos causar una denegación de servicio (uso después de liberación) o posiblemente tener otro impacto no especificado a través de una fuente Type42 manipulada. A use-after-free condition has been encountered in FreeType while fuzzing Type42 fonts.

The (1) cf2_initLocalRegionBuffer and (2) cf2_initGlobalRegionBuffer functions in cff/cf2ft.c in FreeType before 2.5.3 do not properly check if a subroutine exists, which allows remote attackers to cause a denial of service (assertion failure), as demonstrated by a crafted ttf file. Las funciones (1) cf2_initLocalRegionBuffer y (2) cf2_initGlobalRegionBuffer en cff/cf2ft.c en FreeType anterior a 2.5.3 no comprueban debidamente si una subrutina existe, lo que permite a atacantes remotos causar una denegación de servicio (fallo de aserción), tal y como fue demostrado por un archivo ttf manipulado. • http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=135c3faebb96f8f550bd4f318716f2e1e095a969 http://savannah.nongnu.org/bugs/?41697 http://secunia.com/advisories/57447 http://www.openwall.com/lists/oss-security/2014/03/12/4 http://www.ubuntu.com/usn/USN-2148-1 • CWE-20: Improper Input Validation •
