CVE-2011-2072
HighSummary
W systemach Cisco IOS 12.4, 15.0, 15.1, Cisco IOS XE 2.5.x do 3.2.x oraz Cisco Unified Communications Manager (CUCM) 6.x i 7.x przed wersją 7.1(5b)su4, 8.x przed 8.5(1)su2 i 8.6 przed 8.6(1) występuje wyciek pamięci. Atakujący zdalnie mogą spowodować odmowę usługi poprzez wysłanie źle sformułowanej wiadomości SIP.
Risk Assessment
Wyciek pamięci może prowadzić do zużycia pamięci, co skutkuje ponownym uruchomieniem urządzenia lub awarią procesów. To stwarza ryzyko przestoju w działaniu usług i wpływa na dostępność systemów.
Recommendation
Zaleca się aktualizację systemów do najnowszych wersji, które zawierają poprawki eliminujące tę podatność. Należy również monitorować ruch SIP w celu wykrywania potencjalnych ataków.
