Debian Security Advisory DSA 1185-1 security@debian.org

- --------------------------------------------------------------------------
Package : openssl
Vulnerability : denial of service
Problem-Type : remote
Debian-specific: no
CVE ID : CVE-2006-2940 CVE-2006-3738 CVE-2006-4343 CVE-2006-2937
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-2006-2937
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 two denial of service vulnerabilities were discovered.
During the parsing of certain invalid ASN1 structures an error
condition is mishandled. This can result in an infinite loop
which consumes system memory.
Any code which uses OpenSSL to parse ASN1 data from untrusted
sources is affected. This includes SSL servers which enable
client authentication and S/MIME applications.
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 0.9.7e-3sarge3.
For the unstable and testing distributions (sid and etch,
respectively), these problems will be fixed in version 0.9.7k-2 of the
openssl097 compatibility libraries, and version 0.9.8c-2 of the
openssl package.
We recommend that you upgrade your openssl 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
dpkg -i file.deb
will install the referenced file.
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
