Rapporteret den:

6. mar 2006

Berørte pakker:

libtasn1

Sårbar:

Referencer i sikkerhedsdatabaser:

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

Yderligere oplysninger:

Evgeny Legerov har opdaget flere hukommelsestilgange der sker uden for grænserne i DER-dekodningskomponenten i Tiny ASN.1 Library, hvilket gjorde det muligt for angribere at få DER-dekoderen til at gå ned og muligvis udføre vilkårlig kode.

Den gamle stabile distribution (woody) er ikke påvirket af disse problemer.

I den stabile distribution (sarge) er disse problemer rettet i version 2_0.2.10-3sarge1.

I den ustabile distribution (sid) vil disse problemer snart blive rettet.

Vi anbefaler at du opgraderer dine libtasn1-pakker.

Rettet i:

Debian GNU/Linux 3.1 (sarge)
