VMware Security Advisory - ESX patches for OpenSSL, vim and bind resolve several security issues. OpenSSL 0.9.7a-33.24 and earlier does not properly check the return value from the EVP_VerifyFinal function, which could allow a remote attacker to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys. A flaw was discovered in the way Berkeley Internet Name Domain (BIND) checked the return value of the OpenSSL DSA_do_verify function. On systems using DNSSEC, a malicious zone could present a malformed DSA certificate and bypass proper certificate validation, allowing spoofing attacks. Various vulnerabilities were discovered in vim such as format string issues and input validation problems.

3. Problem Description
a. Updated OpenSSL package for the Service Console fixes a
security issue.
OpenSSL 0.9.7a-33.24 and earlier does not properly check the return
value from the EVP_VerifyFinal function, which could allow a remote
attacker to bypass validation of the certificate chain via a
malformed SSL/TLS signature for DSA and ECDSA keys.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-5077 to this issue.
The following table lists what action remediates the vulnerability
(column 4) if a solution is available.
VMware Product Running Replace with/
Product Version on Apply Patch
============= ======== ======= =================
VirtualCenter any Windows not affected
hosted * any any not affected
ESXi 3.5 ESXi not affected
ESX 3.5 ESX affected, patch pending
ESX 3.0.3 ESX ESX303-200903406-SG
ESX 3.0.2 ESX ESX-1008409
ESX 2.5.5 ESX affected, patch pending
* hosted products are VMware Workstation, Player, ACE, Server, Fusion.
b. Update bind package for the Service Console fixes a security issue.
A flaw was discovered in the way Berkeley Internet Name Domain
(BIND) checked the return value of the OpenSSL DSA_do_verify
function. On systems using DNSSEC, a malicious zone could present
a malformed DSA certificate and bypass proper certificate
validation, allowing spoofing attacks.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2009-0025 to this issue.
The following table lists what action remediates the vulnerability
(column 4) if a solution is available.
VMware Product Running Replace with/
Product Version on Apply Patch
============= ======== ======= =================
VirtualCenter any Windows not affected
hosted * any any not affected
ESXi 3.5 ESXi not affected

ESX 2.5.5 ESX affected, patch pending
* hosted products are VMware Workstation, Player, ACE, Server, Fusion.
c. Updated vim package for the Service Console addresses several
security issues.
Several input flaws were found in Visual editor IMproved's (Vim)
keyword and tag handling. If Vim looked up a document's maliciously
crafted tag or keyword, it was possible to execute arbitrary code as
the user running Vim.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-4101 to this issue.
A heap-based overflow flaw was discovered in Vim's expansion of file
name patterns with shell wildcards. An attacker could create a
specially crafted file or directory name, when opened by Vim causes
the application to stop responding or execute arbitrary code.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-3432 to this issue.
Several input flaws were found in various Vim system functions. If a
user opened a specially crafted file, it was possible to execute
arbitrary code as the user running Vim.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-2712 to this issue.
A format string flaw was discovered in Vim's help tag processor. If
a user was tricked into executing the "helptags" command on
malicious data, arbitrary code could be executed with the
permissions of the user running VIM.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2007-2953 to this issue.
The following table lists what action remediates the vulnerability
(column 4) if a solution is available.
