CVSS: 6.8EPSS: 1%CPEs: 1EXPL: 3CVE-2012-0864 – glibc: FORTIFY_SOURCE format string protection bypass via "nargs" integer overflow
https://notcve.org/view.php?id=CVE-2012-0864
Integer overflow in the vfprintf function in stdio-common/vfprintf.c in glibc 2.14 and other versions allows context-dependent attackers to bypass the FORTIFY_SOURCE protection mechanism, conduct format string attacks, and write to arbitrary memory via a large number of arguments. Desbordamiento de enteros en la función vfprint en stdio-common/vfprint.c en glibc v2.14 y otras versiones que permite a isiarios dependientes del contexto eludir el mecanismo de protección FORTIFY_SOURCE, llevar a cabo ataques de cadena de formato y escribir de forma arbitraria en memoria a través de un gran número de argumentos. • http://rhn.redhat.com/errata/RHSA-2012-0393.html http://rhn.redhat.com/errata/RHSA-2012-0397.html http://rhn.redhat.com/errata/RHSA-2012-0488.html http://rhn.redhat.com/errata/RHSA-2012-0531.html http://sourceware.org/git/?p=glibc.git%3Ba=commitdiff%3Bh=7c1f4834d398163d1ac8101e35e9c36fc3176e6e http://sourceware.org/ml/libc-alpha/2012-02/msg00023.html http://www.phrack.org/issues.html?issue=67&id=9#article http://www.securityfocus.com/bid/52201 https://bugzilla.redhat.com/ • CWE-189: Numeric Errors CWE-190: Integer Overflow or Wraparound •
CVSS: 6.8EPSS: 2%CPEs: 4EXPL: 2CVE-2011-2702 – eGlibc - Signedness Code Execution
https://notcve.org/view.php?id=CVE-2011-2702
Integer signedness error in Glibc before 2.13 and eglibc before 2.13, when using Supplemental Streaming SIMD Extensions 3 (SSSE3) optimization, allows context-dependent attackers to execute arbitrary code via a negative length parameter to (1) memcpy-ssse3-rep.S, (2) memcpy-ssse3.S, or (3) memset-sse2.S in sysdeps/i386/i686/multiarch/, which triggers an out-of-bounds read, as demonstrated using the memcpy function. Error de signo de enteros en Glibc anterior a 2.13 y eglibc anterior a 2.13, cuando utiliza la optimización Supplemental Streaming SIMD Extensions 3 (SSSE3), permite a atacantes dependientes de contexto ejecutar código arbitrario a través de un parámetro de longitud negativo en (1) memcpy-ssse3-rep.S, (2) memcpy-ssse3.S, o (3) memset-sse2.S en sysdeps/i386/i686/multiarch/, lo que provoca una lectura fuera de rango, tal y como fue demostrado mediante el uso de la función memcpy. A patch introduced a signedness bug causing any program compiled against the vulnerable version of eglibc and using optimized functions such as memcpy_ssse3 and memcpy-ssse3-back to be potentially vulnerable to unexpected code execution. • https://www.exploit-db.com/exploits/20167 http://seclists.org/oss-sec/2011/q3/123 http://seclists.org/oss-sec/2011/q3/153 http://www.eglibc.org/cgi-bin/viewvc.cgi/trunk/libc/ChangeLog?view=markup&pathrev=10032 http://www.nodefense.org/eglibc.txt http://www.osvdb.org/80718 http://xorl.wordpress.com/2011/08/06/cve-2011-2702-eglibc-and-glibc-signedness-issue https://bugzilla.novell.com/show_bug.cgi?id=706915 https://sourceware.org/git/?p=glibc.git%3Ba=commi • CWE-94: Improper Control of Generation of Code ('Code Injection') •
