Referenser i säkerhetsdatabaser:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 16568.
I Mitres CVE-förteckning: CVE-2006-0645.

Ytterligare information:

Evgeny Legerov upptäckte flera gränsöverskridande minnesåtkomster i DER-avkodningskomponenten i Tiny ASN.1 Library, vilket gjorde det möjligt för angripare att krascha DER-avkodaren och möjligen exekvera godtycklig kod.

Den gamla stabila utgåvan (Woody) påverkas inte av dessa problem.

För den stabila utgåvan (Sarge) har dessa problem rättats i version 2_0.2.10-3sarge1.

För den instabila utgåvan (Sid) kommer dessa problem att rättas inom kort.

Vi rekommenderar att ni uppgraderar era libtasn1-paket.

Debian GNU/Linux 3.1 (sarge)
