we are pleased to announce the availability of release 4.99.2 of Exim.

This is a security release.

It fixes the following vulnerabilities.

CVE-2026-40684     Possible crash with malicious DNS data when using musl libc

   On systems using musl libc (not glibc) due to an oddity in octal printing
   it is possible to crash the connection instance when malformed DNS data
   is present in PTR records.

I sent a note to Rich Felker (musl maintainer) regarding this.
