Caldera Openlinux Server

docview before 1.0-15 allows remote attackers to execute arbitrary commands via shell metacharacters that are processed when converting a man page to a web page.

Squid before 2.3STABLE5 in HTTP accelerator mode does not enable access control lists (ACLs) when the httpd_accel_host and http_accel_with_proxy off settings are used, which allows attackers to bypass the ACLs and conduct unauthorized activities such as port scanning.

Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice.

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.

Linux kernel 2.0, 2.2 and 2.4 with syncookies enabled allows remote attackers to bypass firewall rules by brute force guessing the cookie.

Docview before 1.1-18 in Caldera OpenLinux 3.1.1, SCO Linux 4.0, OpenServer 5.0.7, configures the Apache web server in a way that allows remote attackers to read arbitrary publicly readable files via a certain URL, possibly related to rewrite rules.

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.

startkde in KDE for Caldera OpenLinux 2.3 through 3.1.1 sets the LD_LIBRARY_PATH environment variable to include the current working directory, which could allow local users to gain privileges of other users running startkde via Trojan horse libraries.
