CVE-2008-3521
HighSummary
W funkcji jas_stream_tmpfile w libjasper/base/jas_stream.c w JasPer 1.900.1 występuje warunek wyścigu, który pozwala lokalnym użytkownikom na spowodowanie awarii usługi (wyjście programu) poprzez utworzenie odpowiedniego pliku tymczasowego tmp.XXXXXXXXXX, co powoduje zakończenie działania Jaspera.
Risk Assessment
Podatność ta może prowadzić do zakłócenia działania aplikacji, co w konsekwencji może wpłynąć na dostępność usług w organizacji.
Recommendation
Zaleca się aktualizację do najnowszej wersji JasPer, aby zniwelować ryzyko związane z tą podatnością.

Original NVD description (English source)
Race condition in the jas_stream_tmpfile function in libjasper/base/jas_stream.c in JasPer 1.900.1 allows local users to cause a denial of service (program exit) by creating the appropriate tmp.XXXXXXXXXX temporary file, which causes Jasper to exit. NOTE: this was originally reported as a symlink issue, but this was incorrect. NOTE: some vendors dispute the severity of this issue, but it satisfies CVE's requirements for inclusion.
