Does this matter?

Lower severity and a low EPSS score (0.28%). Track it; it rarely justifies an emergency change on its own.

Description

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, a double-free vulnerability in kerberos_AcceptSecurityContext() and kerberos_InitializeSecurityContextA() (WinPR, winpr/libwinpr/sspi/Kerberos/kerberos.c) can cause a crash in any FreeRDP clients on systems where Kerberos and/or Kerberos U2U is configured (Samba AD member, or krb5 for NFS). The crash is triggered during NLA connection teardown and requires a failed authentication attempt. This issue has been patched in version 3.24.2.
