Description Jan Lieskovsky 2011-10-03 09:53:28 UTC
A denial of service flaw was found in the way Polipo, a lightweight caching web proxy, processed certain HTTP POST / PUT requests. If polipo was configured to allow remote client connections and particular host was allowed to connect to polipo server instance, a remote attacker could use this flaw to cause denial of service (polipo daemon abort due to assertion failure) via specially-crafted HTTP POST / PUT request.
