cmd/go in Go before 1.16.14 and 1.17.x before 1.17.7 can misinterpret branch names that falsely appear to be version tags. This can lead to incorrect access control if an actor is supposed to be able to create branches but not tags.
Curve.IsOnCurve in crypto/elliptic in Go before 1.16.14 and 1.17.x before 1.17.7 can incorrectly return true in situations with a big.Int value that is not a valid field element.
net/http in Go before 1.16.12 and 1.17.x before 1.17.5 allows uncontrolled memory consumption in the header canonicalization cache via HTTP/2 requests.
Go before 1.16.12 and 1.17.x before 1.17.5 on UNIX allows write operations to an unintended file or unintended network connection as a consequence of erroneous closing of file descriptor 0 after file-descriptor exhaustion.
Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation. This affects net.ParseIP and net.ParseCIDR.
The encoding/xml package in Go (all versions) does not correctly preserve the semantics of attribute namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.
The encoding/xml package in Go (all versions) does not correctly preserve the semantics of element namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.
