CVE-2013-0914
CVSS v2.0
3.6
Low
| Vector | AV:L/AC:L/Au:N/C:P/I:P/A:N |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.8.4
Description
The issue allows local users to bypass the ASLR protection mechanism. This is achieved through a crafted application containing a sigaction system call, which exploits the preservation of the sa restorer field value across an exec operation by the flush signal handlers function in kernel/signal.c.
Recommendations
For Linux kernel versions prior to 3.8.4, update to version 3.8.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of the sigaction system call until a patch is available.
