Fixes the following security issues:
- CVE-2021-20270: An infinite loop in SMLLexer in Pygments versions 1.5 to
2.7.3 may lead to denial of service when performing syntax highlighting of
a Standard ML (SML) source file, as demonstrated by input that only
contains the "exception" keyword
- CVE-2021-27291: In pygments 1.1+, fixed in 2.7.4, the lexers used to parse
programming languages rely heavily on regular expressions. Some of the
regular expressions have exponential or cubic worst-case complexity and
are vulnerable to ReDoS. By crafting malicious input, an attacker can
cause a denial of service
Python 2.x support was dropped in pygments 2.6, so adjust (reverse)
dependencies:
Version 2.6
-----------
(released March 8, 2020)
- Running Pygments on Python 2.x is no longer supported.
(The Python 2 lexer still exists.)
