Scroller Gentoo
Gentoo Linux issued a security advisory about a Denial of Service vulnerability in c-icap. Users are urged to upgrade their systems for better security and stability
A vulnerability in c-icap could result in 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.
