Description Paul Bransford 2012-08-26 03:35:57 UTC
Created attachment 607032 [details]
example selinux audit log containing trigger data

Description of problem:
sealert outputs sh errors when an alert description contains parenthesis. Example text that causes error:
SELinux is preventing /usr/sbin/httpd from execute access on the file /var/tmp/ffiasFfSA (deleted).

The console output that occurs when this bug is triggered is:
sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `{ rpm -qf /var/tmp/ffiasFfSA (deleted); } 2>&1'

Version-Release number of selected component (if applicable):
setroubleshoot-server-3.0.47-3.el6_3.x86_64 : SELinux troubleshoot server

How reproducible:
Attempt to parse effected audit log.

Steps to Reproduce:
1. Normal execution of the program (sealert -a /var/log/audit/audit.log
  
Actual results:
Spurious STDERR output

Expected results:
Normal output only


Additional info:
It seems that the end result is acceptable, as sealert displays information about the alert and suggested actions to resolve. The STDERR output doesn't -seem- to cause problems.

Attached is a log containing data triggering this bug.

Notice: this bug was discovered in CentOS, however this should apply in RedHat as well, hence my reporting this upstream.
