I Mitres CVE-ordbog: CVE-2009-0544.
Yderligere oplysninger:

Mike Wiacek opdagede at et bufferoverløb i ARC2-implementeringen i Python Crypto, en samling kryptografiske algoritmer og protokoller til Python, gjorde det muligt at iværksætte lammelsesangreb (denial of service) og potentielt udførelse af vilkårlig kode.

I den stabile distribution (lenny), er dette problem rettet i version 2.0.1+dfsg1-2.3+lenny0.

På grund af tekniske begrænsninger i Debians skripter til arkivhåndtering, kan opdateringen til den gamle stabile distribution (etch) ikke udgives synkront. Problemet vil snart blive rettet i version 2.0.1+dfsg1-1.2+etch0.

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

Vi anbefaler at du opgraderer din python-crypto-pakke.

Rettet i:

Debian GNU/Linux 5.0 (lenny)
