Yderligere oplysninger:

Byrial Jensen har opdaget et par forskudt med en-bufferoverløb i Mutts IMAP-kode, et tekstbaseret postlæsningsprogram som understøtter IMAP, MIME, GPG, PGP og tråde. Denne kode importeres i Balsa-pakken. Dette problem giver en fjern, ondsindet IMAP-server mulighed for at forsage et lammelsesangreb (programmet går ned) og muligvis udføre vilkårlig kode via en specielt fremstillet postmappe.

I den stabile distribution (woody) er dette problem rettet i version 1.2.4-2.2.

Den gamle stabile distribution (potato) lader ikke til at være påvirket af dette problem.

I den ustabile distribution (sid) vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer din balsa-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
