CVE-2023-42444: phonenumber panics on parsing crafted RFC3966 inputs

September 21, 2023 (updated March 11, 2026)

The phonenumber parsing code may panic due to a panic-guarded out-of-bounds access on the phonenumber string.

In a typical deployment of rust-phonenumber, this may get triggered by feeding a maliciously crafted phonenumber over the network, specifically the string .;phone-context=.
