CVE-2010-3847 – glibc - '$ORIGIN' Expansion Privilege Escalation
https://notcve.org/view.php?id=CVE-2010-3847
elf/dl-load.c in ld.so in the GNU C Library (aka glibc or libc6) through 2.11.2, and 2.12.x through 2.12.1, does not properly handle a value of $ORIGIN for the LD_AUDIT environment variable, which allows local users to gain privileges via a crafted dynamic shared object (DSO) located in an arbitrary directory. elf/dl-load.c de ld.so en la Biblioteca GNU C (también conocida como glibc o libc6) hasta v2.11.2, y v2.12.x hasta v2.12.1 no maneja adecuadamente un valor de $ORIGIN de la variable de entorno LD_AUDIT, esto permite a usuarios locales aumentar sus privilegios mediante un objeto dinámico compartido (DSO) ubicado en un directorio aleatorio. The GNU C library dynamic linker suffers from an $ORIGIN expansion vulnerability. • https://www.exploit-db.com/exploits/44024 https://www.exploit-db.com/exploits/44025 https://www.exploit-db.com/exploits/15274 https://www.exploit-db.com/exploits/15304 http://seclists.org/fulldisclosure/2010/Oct/257 http://seclists.org/fulldisclosure/2010/Oct/292 http://seclists.org/fulldisclosure/2010/Oct/294 http://secunia.com/advisories/42787 http://security.gentoo.org/glsa/glsa-201011-01.xml http://sourceware.org/ml/libc-hacker/2010-10/msg00007.html http://s • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-426: Untrusted Search Path •
CVE-2010-3192
https://notcve.org/view.php?id=CVE-2010-3192
Certain run-time memory protection mechanisms in the GNU C Library (aka glibc or libc6) print argv[0] and backtrace information, which might allow context-dependent attackers to obtain sensitive information from process memory by executing an incorrect program, as demonstrated by a setuid program that contains a stack-based buffer overflow error, related to the __fortify_fail function in debug/fortify_fail.c, and the __stack_chk_fail (aka stack protection) and __chk_fail (aka FORTIFY_SOURCE) implementations. Algunos mecanismos run-time de protección de memoria en la Librería C de GNU (también conocido como glibc o libc6) print argv[0] y backtrace information, lo cual permite a atacantes dependientes del contexto obtener información sensible de procesos de memoria mediante la ejecución de un programa incorrecto, como el demostrado por un programa setuid que contiene un error de desbordamiento de búfer basado en pila, relacionado con la función __fortify_fail en debug/fortify_fail.c, y las implementaciones __stack_chk_fail (también conocida como stack protection) y __chk_fail (también conocida como FORTIFY_SOURCE). • http://seclists.org/fulldisclosure/2010/Apr/399 http://www.openwall.com/lists/oss-security/2010/08/25/8 http://www.openwall.com/lists/oss-security/2010/08/31/6 http://www.openwall.com/lists/oss-security/2010/08/31/7 http://www.openwall.com/lists/oss-security/2010/09/02/2 http://www.openwall.com/lists/oss-security/2010/09/02/3 http://www.openwall.com/lists/oss-security/2010/09/02/4 http://www.openwall.com/lists/oss-security/2010/09/02/5 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
