[GLSA-200702-03] Snort: Denial of Service Vulnerability Scan
Vulnerability Scan Summary
Snort: Denial of Service
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200702-03
(Snort: Denial of Service)
Randy Smith, Christian Estan and Somesh Jha discovered that the rule
matching algorithm of Snort can be exploited in a way known as a
"backtracking attack" to perform numerous time-consuming operations.
A remote attacker could send specially crafted network packets, which
would result in the cessation of the detections and the consumption of
the CPU resources.
There is no known workaround at this time.
All Snort users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/snort-22.214.171.124"
Threat Level: Medium
