CVE-2012-1568

Summary

The ExecShield feature in a certain Red Hat patch for the Linux kernel in Red Hat Enterprise Linux (RHEL) 5 and 6 and Fedora 15 and 16 does not properly handle use of many shared libraries by a 32-bit executable file, which makes it easier for context-dependent attackers to bypass the ASLR protection mechanism by leveraging a predictable base address for one of these libraries.

Vulnerable Systems

Operating System

  • Fedoraproject Fedora 15

  • Fedoraproject Fedora 16

  • Redhat Enterprise Linux 5

  • Redhat Enterprise Linux 6
