The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, 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 these issues but has instead relied only on the applicationβs self-reported version number.
