It was discovered that logrotate incorrectly handled certain log file
names when used with the shred option. Local attackers able to create log
files with specially crafted filenames could use this issue to execute
arbitrary code. This issue only affected Ubuntu 10.04 LTS, 10.10, and
11.04. (CVE-2011-1154)

It was discovered that logrotate incorrectly handled certain malformed log
filenames. Local attackers able to create log files with specially crafted
filenames could use this issue to cause logrotate to stop processing log
files, resulting in a denial of service. (CVE-2011-1155)

It was discovered that logrotate incorrectly handled symlinks and hard
links when processing log files. A local attacker having write access to
a log file directory could use this issue to overwrite or read arbitrary
files. This issue only affected Ubuntu 8.04 LTS. (CVE-2011-1548)");
