Description Andrej Nemec 2016-06-21 06:55:20 EDT

Minimatch is a minimal matching utility that works by converting glob expressions into JavaScript RegExp objects. The primary function, minimatch(path, pattern) is vulnerable to ReDoS in the pattern parameter. This is because of the regular expression on line 521 of minimatch.js: /((?:\\{2})*)(\\?)\|/g,. The problematic portion of the regex is ((?:\\{2})*) which matches against //.

Comment 5 Tomas Hoger 2016-07-08 08:42:06 EDT

Upstream commit:

https://github.com/isaacs/minimatch/commit/6944abf9e0694bd22fd9dad293faa40c2bc8a955

Change of the regex does not seem to make much difference, the pattern length restriction is needed to block this issue.
