CVE-2011-0017

Publication date 1 February 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The open_log function in log.c in Exim 4.72 and earlier does not check the return value from (1) setuid or (2) setgid system calls, which allows local users to append log data to arbitrary files via a symlink attack.
