SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/13871/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Exposure of system information, Exposure of
sensitive information, System access

WHERE:
>From local network

OPERATING SYSTEM:
VMware ESX Server 1.x
http://secunia.com/product/1440/
VMware ESX Server 2.x
http://secunia.com/product/2125/

DESCRIPTION:
VMware has acknowledged some vulnerabilities in ESX Server, which can
be exploited to disclose sensitive information in kernel memory,
bypass certain security restrictions, and potentially compromise a
vulnerable system.

1) A "ssl_log()" related format string error within the mod_proxy
hook functions may potentially allow arbitrary code execution.

For more information:
SA12077

Successful exploitation requires that mod_proxy is enabled (not
default setting).

2) Some race conditions and conversion errors within the Linux kernel
when handling 64-bit file offset pointers may disclose large portions
of kernel memory.

For more information:
SA12210

3) An error in mod_ssl allows clients to access a location using any
cipher suite allowed by the virtual host configuration even though
access to that location has been configured to require a specific set
of cipher suites.

For more information:
SA12787

Update to version 2.5 or apply security update.
