CVE-2013-4115
HighSummary
Przepełnienie bufora w funkcji idnsALookup w pliku dns_internal.cc w Squid w wersjach od 3.2 do 3.2.11 oraz od 3.3 do 3.3.6 umożliwia zdalnym atakującym spowodowanie odmowy usługi poprzez długą nazwę w żądaniu wyszukiwania DNS.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do usunięcia pamięci i zakończenia działania serwera, co prowadzi do przerwy w dostępności usług.
Recommendation
Zaleca się aktualizację Squid do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie logów w celu wykrycia potencjalnych prób ataków.

A vulnerability in the ash_authentication library (Elixir) allows an attacker who can plant a remember-me cookie in a victim's browser to replace the victim's authenticated session with one for the attacker's own account. The issue stems from a mismatch between the session keys used by the guard and the reader, causing remember-me sign-in to run on every request.
Original NVD description (English source)
Buffer overflow in the idnsALookup function in dns_internal.cc in Squid 3.2 through 3.2.11 and 3.3 through 3.3.6 allows remote attackers to cause a denial of service (memory corruption and server termination) via a long name in a DNS lookup request.
