Mandriva Linux Security Advisory 2010-060 – The htcpHandleTstRequest function in htcp.c in Squid 2.x and 3.0 through 3.0.STABLE23 allows remote attackers to cause a denial of service (crash) via crafted packets to the HTCP port, which triggers a NULL pointer dereference. Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers. The updated packages have been patched to correct this issue.
