CVE-2012-1568: The ExecShield feature in a certain Red Hat patch for the Linux kernel in Red Hat Enterprise Linux (RHEL) 5...

Security readout for executives and security teams

This issue weakens a memory-protection feature rather than directly compromising a system. On affected Red Hat-patched Linux kernels, certain 32-bit programs using many shared libraries could have a predictable library address, making ASLR bypass easier for an attacker who already has a suitable context. Exposure appears limited to the named Linux distributions and kernels using the relevant ExecShield behavior, especially systems running 32-bit executables with many shared libraries. The bundle does not provide CPEs, package versions, or a CVSS score. Treat as a legacy hardening gap with moderate urgency. It matters most where affected systems host exposed or high-value 32-bit workloads, because it can reduce the effectiveness of exploit mitigations during a separate attack. Mitigation focus: Check Red Hat, Fedora, and Oracle guidance for corrected kernel packages or advisories.; Inventory systems matching RHEL 5, RHEL 6, Fedora 15, or Fedora 16 scope.; Prioritize vendor-supported kernel updates where affected packages are identified..
