Severity:	normal
Title:	c-icap: Denial of Service
Date:	09/19/2014
Bugs:	#455324
ID:	201409-07

Synopsis

A vulnerability in c-icap could result in Denial of Service.

Background

c-icap is an implementation of an ICAP server. It can be used with HTTP proxies that support the ICAP protocol to implement content adaptation and filtering services.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-proxy/c-icap	< 0.2.6	>= 0.2.6	All supported architectures

Description

c-icap contains a flaw in the parse_request() function of request.c that may allow a remote denial of service. The issue is triggered when the buffer fails to contain a ‘ ‘ or ‘?’ symbol, which will cause the end pointer to increase and surpass allocated memory. With a specially crafted request (e.g. via the OPTIONS method), a remote attacker can cause a loss of availability for the program.

Impact

A remote attacker may cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All c-icap users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-proxy/c-icap-0.2.6"
