Gentoo: GLSA-201409-07: c-icap: Denial of Service
Summary
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.
Resolution
All c-icap users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/c-icap-0.2.6"
