DSA-282-1 glibc -- heltalsoverløb

Rapporteret den:

9. apr 2003

Berørte pakker:

Sårbar:

Referencer i sikkerhedsdatabaser:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 7123.
I Mitres CVE-ordbog: CVE-2003-0028.
CERTs noter om sårbarheder, bulletiner og hændelser: VU#516825, CA-2003-10.

Yderligere oplysninger:

eEye Digital Security har opdaget et heltalsoverløb i funktionen xdrmem_getbytes() som også findes i GNU libc. Denne funktion er en del af XDR-koderen/-afkoderen (ekstern datarepræsentation) som er afledt af Suns RPC-implementation. Afhængigt af programmet kan denne sårbarhed få en buffer til at løbe over og kan muligvis udnyttes til udførelse af vilkårlig kode.

I den stabile distribution (woody) er dette problem rettet i version 2.2.5-11.5.

I den gamle stabile distribution (potato) er dette problem rettet i version 2.1.3-25.

I den ustabile distribution (sid) er dette problem rettet i version 2.3.1-16.

Vi anbefaler at du opgraderer dine libc6-pakker.
