A vulnerability in c-icap could result in Denial of Service.
|Package||net-proxy/c-icap on all architectures|
|Affected versions||< 0.2.6|
|Unaffected versions||>= 0.2.6|
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.
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.
A remote attacker may cause a Denial of Service condition.
There is no known workaround at this time.
All c-icap users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/c-icap-0.2.6"
