DSA-2125-1 openssl -- buffer overflow

ID: oval:org.secpod.oval:def:600010Date: (C)2011-01-28   (M)2023-02-20
Class: PATCHFamily: unix




A flaw has been found in the OpenSSL TLS server extension code parsing which on affected servers can be exploited in a buffer overrun attack. This allows an attacker to cause an appliation crash or potentially to execute arbitrary code. However, not all OpenSSL based SSL/TLS servers are vulnerable: A server is vulnerable if it is multi-threaded and uses OpenSSL"s internal caching mechanism. In particular the Apache HTTP server and Stunnel are NOT affected. This upgrade fixes this issue. After the upgrade, any services using the openssl libraries need to be restarted. The checkrestart script from the debian-goodies package or lsof can help to find out which services need to be restarted. A note to users of the tor packages from the Debian backports or Debian volatile: This openssl update causes problems with some versions of tor. You need to update to tor 0.2.1.26-4~bpo50+1 or 0.2.1.26-1~lennyvolatile2, respectively. The tor package version 0.2.0.35-1~lenny2 from Debian stable is not affected by these problems. For the stable distribution , the problem has been fixed in openssl version 0.9.8g-15+lenny9. For the testing distribution and the unstable distribution , this problem has been fixed in version 0.9.8o-3. We recommend that you upgrade your openssl packages.
