CVE-2009-3234

Name of the Vulnerable Software and Affected Versions Linux kernel version 2.6.31-rc1

Description The issue is related to a buffer overflow in the perf copy attr function, which can be triggered by providing "big size data" to the perf counter open system call. This can cause a denial of service (crash) and potentially allow the execution of arbitrary code.

Recommendations For Linux kernel version 2.6.31-rc1, consider applying a patch to fix the buffer overflow issue in the perf copy attr function. As a temporary workaround, restrict access to the perf counter open system call to minimize the risk of exploitation.
