Unknown vulnerability in Apple Mac OS X 10.3.6 server, when using Kerberos authentication and Cyrus IMAP allows local users to access mailboxes of other users.
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.
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.
Safari in Mac OS X before 10.3.5, after sending form data using the POST method, may re-send the data to a GET method URL if that URL is redirected after the POST data and the user uses the forward or backward buttons, which may cause an information leak.
The TCP/IP Networking component in Mac OS X before 10.3.5 allows remote attackers to cause a denial of service (memory and resource consumption) via a "Rose Attack" that involves sending a subset of small IP fragments that do not form a complete, larger packet.
Buffer overflow in digestmd5.c CVS release 1.170 (also referred to as digestmda5.c), as used in the DIGEST-MD5 SASL plugin for Cyrus-SASL but not in any official releases, allows remote attackers to execute arbitrary code.
