CVE-2021-32823: Bindata Project Bindata

Low severity, CVSS 3.7. EPSS: 1.9% chance of exploitation in the next 30 days.

In the bindata RubyGem before version 2.4.10 there is a potential denial-of-service vulnerability. In affected versions it is very slow for certain classes in BinData to be created. For example BinData::Bit100000, BinData::Bit100001, BinData::Bit100002, BinData::Bit<N>. In combination with <user_input>.constantize there is a potential for a CPU-based DoS. In version 2.4.10 bindata improved the creation time of Bits and Integers.

Affected products

• Bindata Project Bindata: before 2.4.10 (fixed in 2.4.10)
• GitLab GitLab: from 12.0, before 13.10.5 (fixed in 13.10.5); from 13.11.0, before 13.11.5 (fixed in 13.11.5); from 13.12.0, before 13.12.2 (fixed in 13.12.2)
