CVE-2011-1155

1.9 · LOW
Published Mar 30, 2011 gentoo CWE-399 EPSS 0.39% (32th pctl)

Overview

CVE-2011-1155 is a low-severity vulnerability affecting gentoo logrotate. It was published on March 30, 2011 and has a CVSS 2.0 base score of 1.9 (LOW).

This vulnerability has a CVSS 2.0 base score of 1.9, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories and patches from gentoo. Update logrotate to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
