Impact When a special crafted packet is received via SslHandler it doesn't correctly handle validation of such a packet in all cases which can lead to a native crash.

Workarounds As workaround its possible to either disable the usage of the native SSLEngine or changing the code from:

SslContext context = ...; SslHandler handler = context.newHandler(....);

to:

SslContext context = ...; SSLEngine engine = context.newEngine(....); SslHandler handler = new SslHandler(engine, ....);

IBM Cognos Analytics 11.2.0, 11.2.1, 11.2.2, 11.2.3, 11.2.4, 12.0.0, 12.0.1, 12.0.2, 12.0.3, and 12.0.4 could allow an authenticated user to cause a denial of service by sending a specially crafted request that would exhaust memory resources.

DISPUTED Mathjax up to v2.7.9 was discovered to contain two Regular expression Denial of Service (ReDoS) vulnerabilities in MathJax.js via the components pattern and markdownPattern. NOTE: the vendor disputes this because the regular expressions are not applied to user input; thus, there is no risk.
