Package	Ecosystem	Affected	Fixed in
github.com/notaryproject/notation-go	Go	>=1.3.0-rc.1, <1.3.0-rc.2	1.3.0-rc.2

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The notation-go library, versions 1.3.0-rc.1 up to but not including 1.3.0-rc.2, can crash during signature verification when CRL-based revocation checking is used. The CRL cache update uses os.Rename, which fails with a cross-device error when the temporary directory and the notation cache directory are on different mount points, and the failure terminates the process. An attacker needs no special access beyond the ability to supply a signature for verification, and the impact is denial of signature verification. Upgrade to notation-go 1.3.0-rc.2 or later.
