Advisory Updated Date: 2014-09-19 10:26 Pacific
Severity:
Important
Issue Overview:
** DISPUTED ** Incomplete blacklist vulnerability in nrpe.c in Nagios Remote Plugin Executor (NRPE) 2.15 and earlier allows remote attackers to execute arbitrary commands via a newline character in the -a option to libexec/check_nrpe. NOTE: this issue is disputed by multiple parties. It has been reported that the vendor allows newlines as "expected behavior." Also, this issue can only occur when the administrator enables the "dont_blame_nrpe" option in nrpe.conf despite the "HIGH security risk" warning within the comments.
Affected Packages:
nrpe
Issue Correction:
Run yum update nrpe to update your system.
