Vulnerability Note VU#247744
OpenSSL may fail to properly parse invalid ASN.1 structures
A vulnerability in OpenSSL may allow an attacker to create a denial-of-service condition.
OpenSSL is an Open Source toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols.
When parsing certain invalid ASN.1 structures, OpenSSL may mishandle an error condition, resulting in an infinite loop. By triggering the infinite loop, an attacker may be able to create a denial-of-service condition.
A remote, unauthenticated attacker may be able create a denial-of-service condition.
See the systems affected section of this document for information about specific vendors. Users who compile OpenSSL from source are encouraged to apply the updates listed in OpenSSL Security Advisory 20060928.
