Background ========== Squid is a full-featured web proxy cache. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-proxy/squid < 2.7.6 >= 2.7.6 Description =========== * The arrayShrink function in lib/Array.c can cause an array to shrink to 0 entries, which triggers an assert error. NOTE: this issue is due to an incorrect fix for CVE-2007-6239 (CVE-2008-1612). * An invalid version number in a HTTP request may trigger an assertion in HttpMsg.c and HttpStatusLine.c (CVE-2009-0478). Impact ====== The issues allows for Denial of Service attacks against the service via an HTTP request with an invalid version number and other specially crafted requests. Workaround ========== There is no known workaround at this time.
