New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
