Synopsis ========
A vulnerability in Logwatch might allow remote attackers to execute arbitrary code.
Background ==========
Logwatch analyzes and reports on system logs.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/logwatch < 7.4.0 >= 7.4.0
Description ===========
logwatch.pl does not properly sanitize log filenames against shell metacharacters before passing them to the "system()" function.
Impact ======
A remote attacker could pass a specially crafted log filename to Logwatch, possibly resulting in execution of arbitrary code with root privileges or a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Logwatch users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/logwatch-7.4.0"
