I Debians fejlsporingssystem: Fejl 328660.
I Mitres CVE-ordbog: CVE-2005-2919, CVE-2005-2920.
CERTs noter om sårbarheder, bulletiner og hændelser: VU#363713.

Yderligere oplysninger:

To sårbarheder er opdaget i Clam AntiVirus, antivirus-scanneren til Unix, designet til at kunne integreres med mailservere til at scanne vedhæftede filer. Der er fundet frem til følgende problemer:

CAN-2005-2919
En potentiel uendelig løkke kunne medføre et lammelsesangreb (denial of service).
CAN-2005-2920
Et bufferoverløb kunne medføre et lammelsesangreb (denial of service).

Den gamle stabile distribution (woody) indeholder ikke ClamAV-pakker.

I den stabile distribution (sarge) er disse problemer rettet i version 0.84-2.sarge.4.

I den ustabile distribution (sid) er disse problemer rettet i version 0.87-1.

Vi anbefaler at du opgraderer din clamav-pakke.

Rettet i:

Debian GNU/Linux 3.1 (sarge)
