Package : pygments
Version : 2.2.0+dfsg-1+deb9u2
CVE ID : CVE-2021-27291
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:
https://security-tracker.debian.org/tracker/pygments
