DSA-183-1 krb5 -- bufferoverløb

Rapporteret den:

Berørte pakker:

krb5

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2002-1235.
CERTs noter om sårbarheder, bulletiner og hændelser: CA-2002-29, VU#875073.

Yderligere oplysninger:

Tom Yu og Sam Hartman fra MIT har opdaget et stack-bufferoverløb mere i funktionen kadm_ser_wrap_in i Kerberos v4-administrationsserveren. Der er fungerende kode til udnyttelse af kadmind-fejlen i omløb, hvorfor den betragtes som alvorlig. MIT krb5-implementationen har understøttelse af version 4, inklusive det komplette v4-bibliotek, serverunderstøttelse af krb4 og begrænset klientunderstøttelse af v4.

Dette problem er rettet i version 1.2.4-5woody3 af den aktuelle stabile distribution (woody) og i version 1.2.6-2 af den ustabile distribution (sid). Den gamle stabile distribution (potato) er ikke påvirket, da den ikke indeholder krb5-pakker.

Vi anbefaler at du omgående opgraderer dine krb5-pakker.

Rettet i:

Debian GNU/Linux 3.0 (woody)
