CVE-2012-0028
Description
From CVE.org
The robust futex implementation in the Linux kernel before 2.6.28 does not properly handle processes that make exec system calls, which allows local users to cause a denial of service or possibly gain privileges by writing to a memory location in a child process.
Statement
This issue did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not have support for robust futexes. It did not affect Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG as they have the backported fixes. This has been addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2012-0107.html.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
