CSRF in runner administration page in all versions of GitLab CE/EE allows an attacker who's able to target GitLab instance administrators to pause/resume runners. Affected versions are >=13.5.0, <13.5.2,>=13.4.0, <13.4.5,<13.3.9.
A vulnerability was discovered in GitLab starting with version 12.2 that allows an attacker to cause uncontrolled resource consumption with a specially crafted file.
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.
