TITLE:
ekg Shell Command Injection and Insecure Temporary File Creation

SECUNIA ADVISORY ID:
SA16102

VERIFY ADVISORY:
http://secunia.com/advisories/16102/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
ekg 1.x
http://secunia.com/product/5326/

DESCRIPTION:
Marcin Owsiany and Wojtek Kaniewski have reported two vulnerabilities
in ekg, which can be exploited by malicious, local users to perform
certain actions on a vulnerable system with escalated privileges.

1) Temporary files are created insecurely in "/tmp" by
contrib/ekgnv.sh and contrib/getekg.sh, and in "/usr/tmp" by
contrib/ekgh. This can be exploited via symlink attacks to create or
overwrite arbitrary files with the privileges of the user executing a
vulnerable script.

2) An error in contrib/scripts/ekgbot-pre1.py can potentially be
exploited to inject shell commands.

The vulnerabilities have been reported in version 1.6rc1. Other
versions may also be affected.

SOLUTION:
Update to version 1.6rc3 or later.
