A vulnerability classified as problematic has been found in Linux Kernel up to 3.12.4 (Operating System). This affects an unknown code block of the file net/ipv4/ping.c. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. This is going to have an impact on confidentiality. The summary by CVE is:
The Linux kernel before 3.12.4 updates certain length values before ensuring that associated data structures have been initialized, which allows local users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call, related to net/ipv4/ping.c, net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and net/ipv6/udp.c.
The weakness was presented 01/07/2014 (oss-sec). The advisory is shared at openwall.com. This vulnerability is uniquely identified as CVE-2013-7263 since 01/05/2014.
