Amazon Linux 1 Security Advisory: ALAS-2012-58
Advisory Release Date: 2012-03-23 14:18 Pacific
Advisory Updated Date: 2014-09-14 15:44 Pacific
Severity:
Medium
Issue Overview:
The ExecShield feature 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.
Affected Packages:
kernel
Issue Correction:
Run yum update kernel to update your system. You will need to reboot your system in order for the new kernel to be running.
