Synopsis

The remote Fedora host is missing a security update.

Description

Update to 0.8.8 (CVE-2012-5642 Bug #887914)

 - Fixes :

 - Alan Jenkins

 - [8c38907] Removed 'POSSIBLE BREAK-IN ATTEMPT' from sshd filter to avoid banning due to misconfigured DNS.
 Close gh-64

 - Yaroslav Halchenko

 - [83109bc] IMPORTANT: escape the content of <matches> (if used in custom action files) since its value could contain arbitrary symbols. Thanks for discovery go to the NBS System security team

 - [b159eab] do not enable pyinotify backend if pyinotify < 0.8.3

 - [37a2e59] store IP as a base, non-unicode str to avoid spurious messages in the console. Close gh-91

 - New features :

 - David Engeset

 - [2d672d1,6288ec2] 'unbanip' command for the client + avoidance of touching the log file to take 'banip' or 'unbanip' in effect. Close gh-81, gh-86

 - Yaroslav Halchenko

 - Enhancements :

 - [2d66f31] replaced uninformative 'Invalid command' message with warning log exception why command actually failed

 - [958a1b0] improved failregex to 'support' auth.backend = 'htdigest'

 - [9e7a3b7] until we make it proper module -- adjusted sys.path only if system-wide run

 - [f52ba99] downgraded 'already banned' from WARN to INFO level. Closes gh-79

 - [f105379] added hints into the log on some failure return codes (e.g. 0x7f00 for this gh-87)

 - Various others: travis-ci integration, script to run tests against all available Python versions, etc

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
