Multiple integer overflows in libtiff 3.6.1 and earlier allow remote attackers to cause a denial of service (crash or memory corruption) via TIFF images that lead to incorrect malloc calls.

Heap-based buffer overflow in Netscape Network Security Services (NSS) library allows remote attackers to execute arbitrary code via a modified record length field in an SSLv2 client hello message.

Multiple vulnerabilities in the RLE (run length encoding) decoders for libtiff 3.6.1 and earlier, related to buffer overflows and integer overflows, allow remote attackers to execute arbitrary code via TIFF files.

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.

The Web Publishing feature in Netscape Enterprise Server 3.x and iPlanet Web Server 4.x allows remote attackers to cause a denial of service (crash) via a wp-html-rend request.

iPlanet Web Server Enterprise Edition and Netscape Enterprise Server 4.0 and 4.1 allows remote attackers to conduct HTTP Basic Authentication via the wp-force-auth Web Publisher command, which provides a distinct attack vector and may make it easier to conduct brute force password guessing without detection.
