DSA-1556-2 perl -- heap-buffertspill

Rapporterat den:

2008-04-24

Berörda paket:

perl

Sårbara:

Referenser i säkerhetsdatabaser:

I Debians felrapporteringssystem: Fel 454792.
I Mitres CVE-förteckning: CVE-2008-1927.

Ytterligare information:

Man har upptäckt att ett buffertspillstillstånd kunde uppstå i Perltolken när den kompilerade vissa reguljära uttryck som innehöll Unicode-tecken. Detta hände även om tecknen i fråga ingick i en variabelreferens skyddad av konstruktionen \Q…\E. När detta fel uppstod kraschade Perltolken vanligtvis, men det går inte att utesluta att det kunde leda till exekvering av godtycklig kod.

För den stabila utgåvan (Etch) har detta problem rättats i version 5.8.8-7etch3.

Den instabila utgåvan (Sid) kommer rättas inom kort.

Vi rekommenderar att ni uppgraderar era perl-paket.
