Security Bulletin: Proof of Concept exploit code, which uses a flaw in glibc that can allow a local unprivileged user to gain root on Linux machine in IBM QRadar Incident Forensics (CVE-2014-5119)

Summary

A vulnerability in the GNU C library (glibc) can allow a local unprivileged user to gain root on some Linux machines. To exploit this flaw, an attacker needs to be able to run unprivileged arbitrary code on the local system.

Vulnerability Details

CVE-ID: CVE-2014-5119

DESCRIPTION: The GNU C Library (glibc) is vulnerable to a heap-based buffer overflow, caused by an off-by-one error in the __gconv_translit_find() function. By setting the CHARSET environment variable to a malicious value, a local attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system with root privileges.
