CVE-2012-2123
7.2 · HIGHOverview
CVE-2012-2123 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 17, 2012 and has a CVSS 2.0 base score of 7.2 (HIGH).
This vulnerability has a CVSS 2.0 base score of 7.2, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
The cap_bprm_set_creds function in security/commoncap.c in the Linux kernel before 3.3.3 does not properly handle the use of file system capabilities (aka fcaps) for implementing a privileged executable file, which allows local users to bypass intended personality restrictions via a crafted application, as demonstrated by an attack that uses a parent process to disable ASLR.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
