VMware ESX 2.1

VMware ESX Server 2.0.x before 2.0.2 and 2.x before 2.5.2 patch 4 stores authentication credentials in base 64 encoded format in the vmware.mui.kid and vmware.mui.sid cookies, which allows attackers to gain privileges by obtaining the cookies using attacks such as cross-site scripting (CVE-2005-3619).

vmware-config.pl in VMware for Linux, ESX Server 2.x, and Infrastructure 3 does not check the return code from a Perl chmod function call, which might cause an SSL key file to be created with an unsafe umask that allows local users to read or modify the SSL key.
