In a second acknowledgement of security vulnerabilities this week, Adobe has released an update to address a potential vulnerability in versions of its Flash Media Server.

Specifically, the newest vulnerability exists in Flash Media Server version 3.5.1 (and earlier) and Adobe Flash Media Interactive Server 3.5.1 and earlier. The update resolves a remote procedure call (RPC) execution issue that could enable an attacker to “execute remote procedures within a server-side ActionScript file running on Flash Media Server,” according to a security bulletin on its support site.

The release notes for the update say further that the fix “updated the server with the OpenSSL Security Advisory recommendations for the vulnerability tracked as CVE-2008-5077 by OpenSSL.” According to the description of the vulnerability, a way to exploit it would be for a hacker "who uses a 'man in the middle' attack to present a malformed SSL/TLS signature from a certificate chain to a vulnerable client, bypassing validation.”

Adobe categorizes this as an important issue, and recommends users update now.

On Tuesday, the company confirmed that Adobe Reader and Adobe Acrobat software contained zero-day vulnerabilities. Adobe said that is was working on a fix for these and that it would announce fixes “as soon as possible."
