Tarantella Secure Global Desktop Enterprise Edition 4.00 and 3.42, and Tarantella Enterprise 3 3.40 and 3.30, when using RSA SecurID and multiple users have the same username, reveals sensitive information during authentication, which allows remote attackers to identify valid usernames and the authentication scheme.

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.

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.

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.

The installation of Tarantella Enterprise 3 allows local users to overwrite arbitrary files via a symlink attack on the "spinning" temporary file.

ttawebtop.cgi in Tarantella Enterprise 3.20 on SPARC Solaris and Linux, and 3.1x and 3.0x including 3.11.903, allows remote attackers to view directory contents via an empty pg parameter.

Race condition in the installation script for Tarantella Enterprise 3 3.01 through 3.20 creates a world-writeable temporary "gunzip" program before executing it, which could allow local users to execute arbitrary commands by modifying the program before it is executed.

Directory traversal vulnerability in ttawebtop.cgi in Tarantella Enterprise 3.00 and 3.01 allows remote attackers to read arbitrary files via a .. (dot dot) in the pg parameter.
