Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
phonenumber versions 0.3.3 up to but not including 0.3.6 can panic when parsing a crafted phone number string, due to a reachable assert check. An attacker who can supply such input, for example over a network, can crash the affected program. Upgrade to phonenumber 0.3.6. The 0.2.x series is not affected.
