OpenSSL Version Rollback and Weak Cryptographic Algorithm Vulnerabilities

OpenSSL contains vulnerabilities that could allow an unauthenticated, remote attacker to bypass security restrictions. The first vulnerability CVE-2005-2969 affects any application using a SL/TLS server implementation provided by OpenSSL versions 0.9.7g and prior. If these implementations have...

OpenSSL: SSL 2.0 protocol rollback

Background OpenSSL is a toolkit implementing the Secure Sockets Layer, Transport Layer Security protocols and a general-purpose cryptography library. Description Applications setting the SSLOPMSIESSLV2RSAPADDING option or the SSLOPALL option, that implies it can be forced by a third-party to...

openssl mitm downgrade attack

The SSL/TLS server implementation in OpenSSL 0.9.7 before 0.9.7h and 0.9.8 before 0.9.8a, when using the SSLOPMSIESSLV2RSAPADDING option, disables a verification step that is required for preventing protocol version rollback attacks, which allows remote attackers to force a client and server to u...

OpenSSL SSL 2.0 rollback (weak cryptography)

Active man-in-the-middle attacker can force rollback to SSL 2.0 protocol with known cryptographic weakness for both client and server if SSLOPMSIESSLV2RSAPADDING or SSLOPALL configuration option is enabled...

Security fix for the ALT Linux 9 package openssl10 version 0.9.7g-alt3

Oct. 11, 2005 Dmitry V. Levin 0.9.7g-alt3 - Applied upstream fix for potential SSL 2.0 rollback during SSL handshake CAN-2005-2969...

JVN#23632449: OpenSSL version rollback vulnerability

Impact When performing communication through a path controlled by an attacker using OpenSSL, the attacker conducting a man-in-the-middle MITM attack can force a client and a server to negotiate the SSL 2.0 protocol even if these parties both support SSL 3.0 or TLS 1.0 to intercept or alter data...

openssl -- potential SSL 2.0 rollback

Vulnerability: Such applications are affected if they use the option SSLOPMSIESSLV2RSAPADDING. This option is implied by use of SSLOPALL, which is intended to work around various bugs in third-party software that might prevent interoperability. The SSLOPMSIESSLV2RSAPADDING option disables a...

Security fix for the ALT Linux 9 package openssl1.1 version 0.9.7g-alt3

Oct. 11, 2005 Dmitry V. Levin 0.9.7g-alt3 - Applied upstream fix for potential SSL 2.0 rollback during SSL handshake CAN-2005-2969...

Mandrake Linux Security Advisory : apache2 (MDKSA-2003:096-1)

A problem was discovered in Apache2 where CGI scripts that output more than 4k of output to STDERR will hang the script's execution which can cause a Denial of Service on the httpd process because it is waiting for more input from the CGI that is not forthcoming due to the locked write call in...
