CVSS: 6.9EPSS: 0%CPEs: 26EXPL: 0CVE-2014-0209 – libXfont: integer overflow of allocations in font metadata file parsing
https://notcve.org/view.php?id=CVE-2014-0209
Multiple integer overflows in the (1) FontFileAddEntry and (2) lexAlias functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 might allow local users to gain privileges by adding a directory with a large fonts.dir or fonts.alias file to the font path, which triggers a heap-based buffer overflow, related to metadata. Múltiples desbordamientos de enteros en las funciones (1) FontFileAddEntry y (2) lexAlias en X.Org libXfont anterior a 1.4.8 y 1.4.9x anterior a 1.4.99.901 podrían permitir a usuarios locales ganar privilegios mediante la adición de un directorio con un archivo fonts.dir o fonts.alias largo a la ruta de la fuente, lo que provoca un desbordamiento de buffer basado en memoria dinámica, relacionado con metadatos. A use-after-free flaw was found in the way libXfont processed certain font files when attempting to add a new directory to the font path. A malicious, local user could exploit this issue to potentially execute arbitrary code with the privileges of the X.Org server. • http://advisories.mageia.org/MGASA-2014-0278.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00073.html http://lists.x.org/archives/xorg-announce/2014-May/002431.html http://rhn.redhat.com/errata/RHSA-2014-1893.html http://seclists.org/fulldisclosure/2014/Dec/23 http://secunia.com/advisories/59154 http://www.debian.org/security/2014/dsa-2927 http://www.mandriva.com/security/advisories?name=MDVSA-2015:145 http://www.oracle.com/technetwork/topics/security/cpujul2014-1 • CWE-189: Numeric Errors CWE-190: Integer Overflow or Wraparound •

CVSS: 5.4EPSS: 0%CPEs: 7EXPL: 1CVE-2014-3144 – Kernel: filter: prevent nla extensions to peek beyond the end of the message
https://notcve.org/view.php?id=CVE-2014-3144
The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced. Las implementaciones de extensión (1) BPF_S_ANC_NLATTR y (2) BPF_S_ANC_NLATTR_NEST en la función sk_run_filter en net/core/filter.c en el kernel de Linux hasta 3.14.3 no comprueban si un valor de cierta longitud es lo suficientemente grande, lo que permite a usuarios locales causar una denegación de servicio (subdesbordamiento de enteros y caída de sistema) a través de instrucciones BPF manipuladas. NOTA: el código afectado fue trasladado a las funciones __skb_get_nlattr y __skb_get_nlattr_nest antes de anunciar la vulnerabilidad. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=05ab8f2647e4221cbdb3856dd7d32bd5407316b3 http://linux.oracle.com/errata/ELSA-2014-3052.html http://secunia.com/advisories/58990 http://secunia.com/advisories/59311 http://secunia.com/advisories/59597 http://secunia.com/advisories/60613 http://www.debian.org/security/2014/dsa-2949 http://www.openwall.com/lists/oss-security/2014/05/09/6 http://www.securityfocus.com/bid/67309 http://www.ubuntu. • CWE-190: Integer Overflow or Wraparound •

The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced. La implementación de extensión BPF_S_ANC_NLATTR_NEST en la función sk_run_filter en net/core/filter.c en el kernel de Linux hasta 3.14.3 utiliza el orden inverso en cierta resta, lo que permite a usuarios locales causar una denegación de servicio (sobrelectura y caída de sistema) a través de instrucciones BPF manipuladas.
