It was discovered that there was a series of denial of service vulnerabilities in Pygments, a popular syntax highlighting library for Python.

A number of regular expressions had exponential or cubic worst-case complexity which could cause a remote denial of service (DoS) when provided with malicious input.

For Debian 9 'Stretch', this problem has been fixed in version 2.2.0+dfsg-1+deb9u2.

We recommend that you upgrade your pygments packages.

For the detailed security status of pygments please refer to its security tracker page at:

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

Multiple security issues were found in MediaWiki, a website engine for collaborative work, which could result in incomplete page/blocking protection, denial of service or cross-site scripting.

An update of the python3 package has been released.
