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
-------------------------------------------------------------------
1 net-proxy/c-icap < 0.2.6 >= 0.2.6
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"
