Detailsinfo

A vulnerability classified as problematic has been found in OpenSSL (Network Encryption Software) (version unknown). This affects the function DSA_do_verify in the library lib/crypto/c_src/crypto_drv.c. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality. The summary by CVE is:

** DISPUTED ** lib/crypto/c_src/crypto_drv.c in erlang does not properly check the return value from the OpenSSL DSA_do_verify function, which might allow remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077. NOTE: a package maintainer disputes this issue, reporting that there is a proper check within the only code that uses the applicable part of crypto_drv.c, and thus "this report is invalid."

The weakness was disclosed 01/15/2009 (oss-sec). It is possible to read the advisory at openwall.com. This vulnerability is uniquely identified as CVE-2009-0130 since 01/15/2009. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The real existence of this vulnerability is still doubted at the moment. The vulnerability scanner Nessus provides a plugin with the ID 35310 (CentOS 3 / 4 / 5 : openssl (CESA-2009:0004)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published 3 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (35310). The entries VDB-45926, VDB-45925, VDB-45924 and VDB-45798 are pretty similar. Be aware that VulDB is the high quality source for vulnerability data.
