VMware ESX Server 2.5.4 Patch 1 fixes the following:
ucd-snmp -- A denial of service bug was found in the way ucd-snmp uses network stream protocols. A remote attacker could send a ucd-snmp agent a specially crafted packet which will cause the agent to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CAN-2005-2177 to this issue.
XFree86 -- An integer overflow flaw in the way the XFree86 server processes PCF font files was discovered. A malicious authorized client could exploit this issue to cause a denial of service (crash) or potentially execute arbitrary code with root privileges on the XFree86 server. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-3467 to this issue.
An AMD fxsave/restore security vulnerability. The instructions fxsave and fxrstor on AMD CPUs are used to save or restore the FPU registers (FOP, FIP and FDP). On AMD Opteron processors, these instructions do not save/restore some exception related registers unless an exception is currently being serviced. This could allow a local attacker to partially monitor the execution path of FPU processes, possibly allowing them to obtain sensitive information being passed through those processes. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-1056 to this issue.
A minor info leak in socket name handling in the network code (CVE-2006-1342).
A minor info leak in socket option handling in the network code (CVE-2006-1343).
A directory traversal vulnerability in smbfs that allowed a local user to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences (CVE-2006-1864). A flaw in the mprotect system call that allowed to give write permission to a readonly attachment of shared memory (CVE-2006-2071).
The non-security-related fixes are documented on the patch download page.
VMware ESX Server 2.1.3 Patch 2 fixes the following:
Openssh -- A bug was found in the way the OpenSSH server handled the MaxStartups and LoginGraceTime configuration variables. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CAN-2004-2069 to this issue.
samba -- A denial of service bug was found in the way the smbd daemon tracks active connections to shares. It was possible for a remote attacker to cause the smbd daemon to consume a large amount of system memory by sending carefully crafted smb requests. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-3403 to this issue.
Python -- An integer overflow flaw was found in Python's PCRE library that could be triggered by a maliciously crafted regular expression. On systems that accept arbitrary regular expressions from untrusted users, this could be exploited to execute arbitrary code with the privileges of the application using the library. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2005-2491 to this issue.
ucd-snmp -- A denial of service bug was found in the way ucd-snmp uses network stream protocols. A remote attacker could send a ucd-snmp agent a specially crafted packet which will cause the agent to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CAN-2005-2177 to this issue.
XFree86 -- An integer overflow flaw in the way the XFree86 server processes PCF font files was discovered. A malicious authorized client could exploit this issue to cause a denial of service (crash) or potentially execute arbitrary code with root privileges on the XFree86 server. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-3467 to this issue.

A minor info leak in socket name handling in the network code (CVE-2006-1342).
A minor info leak in socket option handling in the network code (CVE-2006-1343). A directory traversal vulnerability in smbfs that allowed a local user to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences (CVE-2006-1864).
A flaw in the mprotect system call that allowed to give write permission to a readonly attachment of shared memory (CVE-2006-2071).
