Release Date: 2016-01-07 Last Updated: 2016-01-07 Potential Security Impact: Remote Denial of Service (DoS) Source: Hewlett Packard Enterprise, Product Security Response Team VULNERABILITY SUMMARY Potential security vulnerabilities have been identified with HP-UX Web Server Suite running Apache on HP-UX 11iv3. These vulnerabilities could be exploited remotely to create a Denial of Service (DoS) and other impacts including: The TLS vulnerability using US export-grade 512-bit keys in Diffie-Hellman key exchange known as "Logjam" could be exploited remotely to allow unauthorized modification. The RC4 stream cipher vulnerability in SSL/TLS known as "Bar Mitzvah" could be exploited remotely to allow disclosure of information. Apache does not properly parse chunk headers, which allows remote attackers to conduct HTTP request smuggling attacks via a crafted request, related to mishandling of large chunk-size values and invalid chunk-extension characters.
