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 •
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 •

CVSS: 6.9EPSS: 0%CPEs: 39EXPL: 0CVE-2014-9529 – kernel: use-after-free during key garbage collection
https://notcve.org/view.php?id=CVE-2014-9529
Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key. Condición de carrera en la función key_gc_unused_keys en security/keys/gc.c en el kernel de Linux hasta 3.18.2 permite a usuarios locales causar una denegación de servicio (corrupción de memoria o pánico) o posiblemente tener otro impacto no especificado a través de comandos keyctl que provocan el acceso a un miembro de la estructura clave durante la recogida de basura de una clave. A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a3a8784454692dd72e5d5d34dcdab17b4420e74c http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147864.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147973.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://rhn.redhat.com/errata/RHSA-2015-0864.html http://rhn.redhat.com/errata/RHSA-2015-1137.html http://rhn.redhat.com/errata/RHSA-2015-1138& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
