Ubuntu 8.04 LTS : openssl vulnerabilities (USN-620-1)

medium Nessus Plugin ID 33389

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that OpenSSL was vulnerable to a double-free when using TLS server extensions. A remote attacker could send a crafted packet and cause a denial of service via application crash in applications linked against OpenSSL. Ubuntu 8.04 LTS does not compile TLS server extensions by default. (CVE-2008-0891)

It was discovered that OpenSSL could dereference a NULL pointer. If a user or automated system were tricked into connecting to a malicious server with particular cipher suites, a remote attacker could cause a denial of service via application crash. (CVE-2008-1672).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
