Debian Security Advisory DSA-1195-1 security@debian.org
http://www.debian.org/security/ Noah Meyerhans

Package : openssl096
Vulnerability : denial of service (multiple)
Problem-Type : remote
Debian-specific: no
CVE ID : CVE-2006-2940 CVE-2006-3738 CVE-2006-4343
Multiple vulnerabilities have been discovered in the OpenSSL
cryptographic software package that could allow an attacker to launch
a denial of service attack by exhausting system resources or crashing
processes on a victim's computer.
CVE-2006-3738
Tavis Ormandy and Will Drewry of the Google Security Team
discovered a buffer overflow in SSL_get_shared_ciphers utility
function, used by some applications such as exim and mysql. An
attacker could send a list of ciphers that would overrun a
buffer.
CVE-2006-4343
Tavis Ormandy and Will Drewry of the Google Security Team
discovered a possible DoS in the sslv2 client code. Where a
client application uses OpenSSL to make a SSLv2 connection to
a malicious server that server could cause the client to
crash.
CVE-2006-2940
Dr S N Henson of the OpenSSL core team and Open Network
Security recently developed an ASN1 test suite for NISCC
(www.niscc.gov.uk). When the test suite was run against
OpenSSL a DoS was discovered.
Certain types of public key can take disproportionate amounts
of time to process. This could be used by an attacker in a
denial of service attack.
For the stable distribution (sarge) these problems have been fixed in
version 0.9.6m-1sarge4
This package exists only for compatibility with older software, and is
not present in the unstable or testing branches of Debian.
We recommend that you upgrade your openssl096 package. Note that
services linking against the openssl shared libraries will need to be
restarted. Common examples of such services include most Mail
Transport Agents, SSH servers, and web servers.
Upgrade instructions
- --------------------
wget url
will fetch the file for you
