| Revision Date: | 2012-05-17 | Version: | 1 | | Title: | CVE-2012-2123 on Ubuntu 16.04 LTS (xenial) - medium. | | 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. Steve Grubb reported a flaw with Linux fscaps (file system base capabilities) when used to increase the permissions of a process. For application on which fscaps are in use a local attacker can disable address space randomization to make attacking the process with raised privileges easier.
