Official Description
The writeState function in logrotate.c in logrotate 3.7.9 and earlier might allow context-dependent attackers to cause a denial of service (rotation outage) via a (1) \n (newline) or (2) \ (backslash) character in a log filename, as demonstrated by a filename that is automatically constructed on the basis of a hostname or virtual machine name.
Technical Analysis
CVE-2011-1155 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
