Conectiva alert CLA-2003:759 (openssl)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : openssl SUMMARY : Denial of service vulnerability DATE : 2003-10-03 16:30:00 ID : CLA-2003:759 RELEVANT RELEASES : 7.0, 8 - ------------------------------------------------------------------------- DESCRIPTION OpenSSL[1] implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as full-strength general purpose cryptography functions. It is used (as a library) by several projects, like Apache, OpenSSH, Bind, OpenLDAP and many others clients and servers programs. Patrick Hornick reported[2] a denial of service vulnerability in OpenSSL versions prior to 0.9.6f. An attacker can contruct a specially crafted SSLv2 CLIENT_MASTER_KEY message that when parsed by a program using OpenSSL can trigger a call to the die() function, which aborts the program as an attempt to mitigate the exploitation of potential parsing errors. This update includes patches that remove the calls to die() and replaces them with error reporting/treatment (as in new version of OpenSSL), thus avoiding the closing of applications when receiving such malicious messages. Please note that this issue has no direct relation with the recently fixed vulnerabilities[3] in the OpenSSL ASN.1 parsing code. SOLUTION It is recommended that all users upgrade their openssl packages. Please note that it is necessary to restart services which use the library (such as the apache web server with SSL enabled) so that the new, fixed, version is used. A list of such applications can be obtained after the upgrade with the following command: lsof | grep libssl The first column will contain the name of the application that needs to be restarted. If there is any doubt about which application has to be restarted or how to do it, we recommend that the system be rebooted.
