DSA-1556-2 perl -- heap-bufferoverløb

Rapporteret den:

24. apr 2008

Berørte pakker:

perl

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 454792.
I Mitres CVE-ordbog: CVE-2008-1927.

Yderligere oplysninger:

Man opdagede at Perl-fortolkeren kunne løbe ind i en bufferoverløbstilstand når den kompilede visse regulære udtryk indholde Unicode-tegn. Dette skete også hvis de problematiske tegn var indeholdt i en variabelreference beskyttet af citatnotationen \Q...\E. Når denne tilstand opstod, gik Perl-fortolkeren typisk ned, men vilkårlig udførelse af kode kan ikke udelukkes.

I den stabile distribution (etch), er dette problem rettet i version 5.8.8-7etch3.

Den ustabile distribution (sid) vil snart blive rettet.

Vi anbefaler at du opgraderer dine perl-pakker.
