DSA-1970-1 openssl -- lammelsesangreb

Rapporteret den:

13. jan 2010

Berørte pakker:

openssl

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2009-4355.

Yderligere oplysninger:

Man opdagede at en betydelig hukommelseslækage kunne opstå i OpenSSL, relateret til geninitialiseringen af zlib. Det kunne medføre en fjernudnytbar lammelsesangrebssårbarhed, når man anvender Apaches httpd-server i en opsætning, hvor mod_ssl, mod_php5 og udvidelsen php5-curl er indlæst.

Den gamle stabile distribution (etch) er ikke påvirket af dette problem.

I den stabile distribution (lenny), er dette problem rettet i version 0.9.8g-15+lenny6.

Pakkerne til arm-arkitekturen er ikke klar endnu, men vil blive gjort tilgængelige så snart de er klar..

I distributionen testing (squeeze) og i den ustabile distribution (sid), vil dette problem snart blive rettet. Problemet lader ikke til at være udnytbart med apache2-pakken, der er i squeeze/sid.

Vi anbefaler at du opgraderer dine openssl-pakker. Du skal også genstarte din Apache-httpd-server, for at sikre at den anvender de opdaterede biblioteker.
