Caldera : Security Vulnerabilities, CVEs, (Denial of service)

SCO UnixWare 7.1.1 and Open UNIX 8.0.0 allows local users to cause a denial of service via an rcp call on /proc.

Preboot eXecution Environment (PXE) server allows remote attackers to cause a denial of service (crash) via certain DHCP packets from Voice-Over-IP (VOIP) phones.

Vulnerability in the MIT-SHM extension of the X server on Linux (XFree86) 4.2.1 and earlier allows local users to read and write arbitrary shared memory, possibly to cause a denial of service or gain privileges.

lpsystem in OpenUnix 8.0.0 allows local users to cause a denial of service and possibly execute arbitrary code via a long command line argument.

BitchX IRC client does not properly cleanse an untrusted format string, which allows remote attackers to cause a denial of service via an invite to a channel whose name includes special formatting characters.

Linux gpm program allows local users to cause a denial of service by flooding the /dev/gpmctl device with STREAM sockets.

Buffer overflow in the XDMCP parsing code of GNOME gdm, KDE kdm, and wdm allows remote attackers to execute arbitrary commands or cause a denial of service via a long FORWARD_QUERY request.

The IDENT server in Caldera Linux 2.3 creates multiple threads for each IDENT request, which allows remote attackers to cause a denial of service.

Denial of service in WU-FTPD via the SITE NEWER command, which does not free memory properly.

XFree86 xfs command is vulnerable to a symlink attack, allowing local users to create files in restricted directories, possibly allowing them to gain privileges or cause a denial of service.
