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.

Potential internet exposure

Potential exposure only — not proof of vulnerability.Shodan results indicate potentially internet-exposed products, not confirmed vulnerable systems. They do not confirm that any returned system is vulnerable to CVE-2011-1155.

Product-level CPE searches intentionally omit version fields and NVD version-range or configuration certainty. Verify the exact product version and configuration independently.
