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...

Debian Security Advisory DSA 1189-1 (openssh-krb5)

The remote host is missing an update to openssh-krb5 announced via advisory DSA 1189-1. Several remote vulnerabilities have been discovered in OpenSSH, a free implementation of the Secure Shell protocol, which may lead to denial of service and potentially the execution of arbitrary code. The Comm...

FreeBSD : openssh -- multiple vulnerabilities (32db37a5-50c3-11db-acf3-000c6ec775d9)

Problem Description The CRC compensation attack detector in the sshd8 daemon, upon receipt of duplicate blocks, uses CPU time cubic in the number of duplicate blocks received. CVE-2006-4924 A race condition exists in a signal handler used by the sshd8 daemon to handle the LoginGraceTime option,...

security flaw

net/ipv4/netfilter/ipconntrackcore.c in Linux kernel 2.4 and 2.6, and possibly net/ipv4/netfilter/nfconntrackl3protoipv4.c in 2.6, does not clear sockaddrin.sinzero before returning IPv4 socket names from the getsockopt function with SOORIGINALDST, which allows local users to obtain portions of...

FreeBSD : openssl -- potential SSL 2.0 rollback (60e26a40-3b25-11da-9484-00123ffe8333)
