I Mitres CVE-förteckning: CVE-2006-0645.

Ytterligare information:

Evgeny Legerov upptäckte flera gränsöverskridande minnesåtkomster i DER-avkodningskomponenten i Tiny ASN.1 Library, vilka även förekommer i GnuTLS, GNUs implementation av protokollen Transport Layer Security (TLS) 1.0 och Secure Sockets Layer (SSL) 3.0, 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 1.0.16-13.2.

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

Vi rekommenderar att ni uppgraderar era gnutls-paket.

Debian GNU/Linux 3.1 (sarge)
