CVE-2013-7265

CVSS v2.0

4.9

Média

VetorAV:L/AC:L/Au:N/C:C/I:N/A:N
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.12.4
Description The issue allows local users to obtain sensitive information from kernel stack memory. This is due to the pn recvmsg function updating a certain length value before ensuring that an associated data structure has been initialized. The sensitive information can be accessed via system calls such as recvfrom, recvmmsg, or recvmsg.
Recommendations For Linux kernel versions prior to 3.12.4, update to version 3.12.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of the pn recvmsg function until a patch is available. Additionally, restrict access to the recvmmsg and recvmsg system calls to minimize the risk of exploitation.
