Directory traversal vulnerability in UnZip 5.50 allows attackers to overwrite arbitrary files via invalid characters between two . (dot) characters, which are filtered and result in a ".." sequence.

The key validation code in GnuPG before 1.2.2 does not properly determine the validity of keys with multiple user IDs and assigns the greatest validity of the most valid user ID, which prevents GnuPG from warning the encrypting user when a user ID does not have a trusted path.

Apache 2 before 2.0.47, when running on an IPv6 host, allows attackers to cause a denial of service (CPU consumption by infinite loop) when the FTP proxy server fails to create an IPv6 socket.

The prefork MPM in Apache 2 before 2.0.47 does not properly handle certain errors from accept, which could lead to a denial of service.

Off-by-one error in the xlog function of mountd in the Linux NFS utils package (nfs-utils) before 1.0.4 allows remote attackers to cause a denial of service and possibly execute arbitrary code via certain RPC requests to mountd that do not contain newlines.

ypserv NIS server before 2.7 allows remote attackers to cause a denial of service via a TCP client request that does not respond to the server, which causes ypserv to block.

The mxcsr code in Linux kernel 2.4 allows attackers to modify CPU state registers via a malformed address.

Unknown vulnerability in the TTY layer of the Linux kernel 2.4 allows attackers to cause a denial of service ("kernel oops").

The ioperm system call in Linux kernel 2.4.20 and earlier does not properly restrict privileges, which allows local users to gain read or write access to certain I/O ports.

Vulnerability in the apr_psprintf function in the Apache Portable Runtime (APR) library for Apache 2.0.37 through 2.0.45 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long strings, as demonstrated using XML objects to mod_dav, and possibly other vectors.

The route cache implementation in Linux 2.4, and the Netfilter IP conntrack module, allows remote attackers to cause a denial of service (CPU consumption) via packets with forged source addresses that cause a large number of hash table collisions.

Memory leak in xinetd 2.3.10 allows remote attackers to cause a denial of service (memory consumption) via a large number of rejected connections.

KDE 2 and KDE 3.1.1 and earlier 3.x versions allows attackers to execute arbitrary commands via (1) PostScript (PS) or (2) PDF files, related to missing -dPARANOIDSAFER and -dSAFER arguments when using the kghostview Ghostscript viewer.

Buffer overflow in the call_trans2open function in trans2.c for Samba 2.2.x before 2.2.8a, 2.0.10 and earlier 2.0.x versions, and Samba-TNG before 0.3.2, allows remote attackers to execute arbitrary code.

Multiple buffer overflows in Samba before 2.2.8a may allow remote attackers to execute arbitrary code or cause a denial of service, as discovered by the Samba team and a different vulnerability than CVE-2003-0201.

CUPS before 1.1.19 allows remote attackers to cause a denial of service via a partial printing request to the IPP port (631), which does not time out.

tcpdump does not properly drop privileges to the pcap user when starting up.

Apache 2 before 2.0.47, and certain versions of mod_ssl for Apache 1.3, do not properly handle "certain sequences of per-directory renegotiations and the SSLCipherSuite directive being used to upgrade from a weak ciphersuite to a strong one," which could cause Apache to use the weak ciphersuite.

OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack.

The authentication module for Apache 2.0.40 through 2.0.45 on Unix does not properly handle threads safely when using the crypt_r or crypt functions, which allows remote attackers to cause a denial of service (failed Basic authentication with valid usernames and passwords) when a threaded MPM is used.
