1.5.5 (Patch/Security Release) - hwb() ReDos patch (low-severity)
Release notes copied verbatim from the commit message, which can be found here: 0789e21284c33d89ebc4ab4ca6f759b9375ac9d3
Discovered by Yeting Li, c/o Colin Ife via Snyk.io.
A ReDos (Regular Expression Denial of Service) vulnerability was responsibly disclosed to me via email by Colin on Mar 5 2021 regarding an exponential time complexity for linearly increasing input lengths for
hwb()
color strings.Strings reaching more than 5000 characters would see several milliseconds of processing time; strings reaching more than 50,000 characters began seeing 1500ms (1.5s) of processing time.
The cause was due to a the regular expression that parses hwb() strings - specifically, the hue value - where the integer portion of the hue value used a 0-or-more quantifier shortly thereafter followed by a 1-or-more quantifier.
This caused excessive backtracking and a cartesian scan, resulting in exponential time complexity given a linear increase in input length.
Thank you Yeting Li and Colin Ife for bringing this to my attention in a secure, responsible and professional manner.
A CVE will not be assigned for this vulnerability.
1.5.4 (Patch Release)
- Removes rounding of alpha values in RGBA hex (
#rrggbbaa
) and condensed-hex (#rgba
) parsers, which caused certain unique inputs to result in identical outputs (see https://github.com/qix-/color/issues/174).
