I Mitres CVE-ordbog: CVE-2006-1614, CVE-2006-1615, CVE-2006-1630.

Yderligere oplysninger:

Flere sårbarheder der kan fjernudnyttes er opdaget i antivirus-værktøjssættet ClamAV, hvilket kunne føre til et lammelsesangreb (denial of service) og potentielt udførelse af vilkårlig kode. Projektet Common Vulnerabilities and Exposures har fundet frem til følgende problemer:

CVE-2006-1614
Damian Put har opdaget et heltalsoverløb i PE-header-fortolkeren. Dette kunne kun udnyttes hvis valgmuligheden ArchiveMaxFileSize var slået fra.
CVE-2006-1615
Der er opdaget formatstrengssårbarheder i logningskoden, de kunne føre til udførelse af vilkårlig kode.
CVE-2006-1630
David Luyer har opdaget at ClamAV kunne narres til at tilgå hukommelse på ulovlig vis i funktionen cli_bitset_set(), hvilket kunne føre til et lammelsesangreb.

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

I den stabile distribution (sarge) er disse problemer rettet i version 0.84-2.sarge.8.

I den ustabile distribution (sid) er disse problemer rettet i version 0.88.1-1.

Vi anbefaler at du opgraderer din clamav-pakke.
