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.

Security readout for executives and security teams

CVE-2011-0536 is a local privilege escalation issue in certain modified glibc/libc6 dynamic loader implementations. A local account could potentially gain elevated privileges when a vulnerable setuid or setgid program uses $ORIGIN in RPATH or RUNPATH. It is mainly a legacy Linux and appliance risk, not a remote network flaw. Exposure is most likely on legacy systems running vulnerable vendor glibc/libc6 packages, including the Red Hat versions named in the CVE description. Vendor references also exist for Ubuntu, Debian, Mandriva, and VMware, so validate against each platform's advisory rather than assuming broad current exposure. Treat this as a high-priority legacy platform cleanup item. It is not internet-facing by itself, but a local user or compromised account could use it to escalate privileges on vulnerable systems. Prioritize shared servers, appliances, and systems with many local users. Mitigation focus: Apply the relevant vendor glibc/libc6 security update for affected legacy systems.; Review Red Hat, Ubuntu, Debian, Mandriva, and VMware advisories for platform-specific fixes.; Reduce local shell access on systems pending validation or patching..
