CVE-2012-5833
HighSummary
Implementacja texImage2D w subsystemie WebGL w Mozilla Firefox przed wersją 17.0, Firefox ESR 10.x przed 10.0.11, Thunderbird przed 17.0, Thunderbird ESR 10.x przed 10.0.11 oraz SeaMonkey przed 2.14 nieprawidłowo współdziała z sterownikami Mesa. To pozwala zdalnym atakującym na wykonanie dowolnego kodu lub spowodowanie odmowy usługi (uszkodzenie pamięci i awaria aplikacji) poprzez wywołania funkcji z określonymi wartościami parametru level.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, umożliwiając zdalnym atakującym przejęcie kontroli nad systemem lub zakłócenie jego działania. Może to prowadzić do utraty danych oraz przestoju w działaniu aplikacji.
Recommendation
Zaleca się aktualizację przeglądarek Mozilla Firefox, Thunderbird i SeaMonkey do najnowszych wersji, aby usunąć tę podatność. Dodatkowo warto monitorować i ograniczać dostęp do aplikacji, które mogą być narażone na ataki wykorzystujące tę lukę.

Original NVD description (English source)
The texImage2D implementation in the WebGL subsystem in Mozilla Firefox before 17.0, Firefox ESR 10.x before 10.0.11, Thunderbird before 17.0, Thunderbird ESR 10.x before 10.0.11, and SeaMonkey before 2.14 does not properly interact with Mesa drivers, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via function calls involving certain values of the level parameter.
