CVE-2011-0017

Name of the Vulnerable Software and Affected Versions Exim versions 4.72 and earlier

Description The issue concerns the open log function in log.c, which fails to check the return value from setuid or setgid system calls. This allows local users to append log data to arbitrary files via a symlink attack.

Recommendations For Exim versions 4.72 and earlier, consider updating to a version where this issue is fixed, as the current version allows for a symlink attack due to the lack of return value checks from setuid or setgid system calls. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
