glibc: svc_run() produces high cpu usage when accept() fails with EMFILE error

A denial of service flaw was found in the remote procedure call RPC implementation in glibc. A remote attacker able to open a large number of connections to an RPC service that is using the RPC implementation from glibc, could use this flaw to make that service use an excessive amount of CPU time...

FreeBSD : Multiple implementations -- DoS via hash algorithm collision (91be81e7-3fea-11e1-afc7-2c4138874f7d)

oCERT reports : A variety of programming languages suffer from a denial-of-service DoS condition against storage functions of key/value pairs in hash data structures, the condition can be leveraged by exploiting predictable collisions in the underlying hashing algorithms. The issue finds particul...
