NewStart CGSL CORE 5.04 / MAIN 5.04 : logrotate Multiple Vulnerabilities (NS-SA-2021-0108)

medium Nessus Plugin ID 154524

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has logrotate packages installed that are affected by multiple vulnerabilities:

- Race condition in the createOutputFile function in logrotate.c in logrotate 3.7.9 and earlier allows local users to read log data by opening a file before the intended permissions are in place. (CVE-2011-1098)

- The shred_file function in logrotate.c in logrotate 3.7.9 and earlier might allow context-dependent attackers to execute arbitrary commands via shell metacharacters in a log filename, as demonstrated by a filename that is automatically constructed on the basis of a hostname or virtual machine name.
(CVE-2011-1154)

- 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. (CVE-2011-1155)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL logrotate packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
