Unspecified vulnerability in Citrix Access Gateway 4.5 Advanced Edition, and 4.2 with Advanced Access Control (AAC) 4.2, when deployed on the Access Gateway appliance 4.2 through 4.2.2 allows remote authenticated users to "gain access to data" and obtain sensitive information via unspecified vectors.

Unspecified vulnerability in Citrix Access Gateway with Advanced Access Control (AAC) 4.2 before 20060914, when AAC is configured to use LDAP authentication, allows remote attackers to bypass authentication via unknown vectors.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.

The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.

The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.

OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.
