(from https://nvd.nist.gov/vuln/detail/CVE-2022-25314) In Expat (aka libexpat) before 2.4.5, there is an integer overflow in copyString.
In copyString of xmlparse.c, there is a possible memory corruption due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
