Descriptions

Multiple untrusted search path vulnerabilities in elf/dl-object.c in certain modified versions of the GNU C Library (aka glibc or libc6), including glibc-2.5-49.el5_5.6 and glibc-2.12-1.7.el6_0.3 in Red Hat Enterprise Linux, allow local users to gain privileges via a crafted dynamic shared object (DSO) in a subdirectory of the current working directory during execution of a (1) setuid or (2) setgid program that has $ORIGIN in (a) RPATH or (b) RUNPATH within the program itself or a referenced library. NOTE: this issue exists because of an incorrect fix for CVE-2010-3847.

Múltiples vulnerabilidades de ruta (path) de búsqueda no confiable en el archivo elf/dl-object.c en ciertas versiones modificadas de la Biblioteca C de GNU (también se conoce como glibc o libc6), incluyendo glibc-2.5-49.el5_5.6 y glibc-2.12-1.7.el6_0.3 en Red Hat Enterprise Linux, permite a los usuarios locales alcanzar privilegios por medio de un dynamic shared object (DSO) diseñado en un subdirectorio del directorio de trabajo actual durante la ejecución de un programa (1) setuid o (2) setgid que tiene $ORIGIN en (a) RPATH o (b) RUNPATH dentro del propio programa o una biblioteca referenciada. NOTA: este problema se presenta debido a una solución incorrecta de CVE-2010-3847.

Multiple vulnerabilities have been found in GNU C Library, the worst of which allowing arbitrary code execution and privilege escalation. Versions less than 2.15-r3 are affected.
