CVE ID         : CVE-2021-32837

Erik Krogh Kristensen and Rasmus Petersen from the GitHub Security Lab
discovered a ReDoS (Regular Expression Denial of Service) vulnerability
in python-mechanize, a library to automate interaction with websites
modeled after the Perl module WWW::Mechanize, which could lead to
Denial of Service when parsing a malformed authentication header.

For Debian 10 buster, this problem has been fixed in version

We recommend that you upgrade your python-mechanize packages.
