oss-security is *not* the MITRE CNA team, it's a public mailing list with public
archives.

Espilon VR reports a remote, pre-authentication denial-of-service defect (with a latent,
weak out-of-bounds write side effect) in the CIM-XML request parser of SBLIM SFCB. Upstream
is abandoned (last release 1.4.9 in 2017), so we are requesting a CVE from MITRE and
notifying the distributions that still ship sfcb, which are the realistic remediation path.
A one-line fix accompanies this report. We propose a 90-day timeline expiring 2027-02-07,
adjustable. A 17-byte PoC and a faithful harness are available on request.

Too late, by sending this mail to oss-security you publicly disclosed today,
without any coordination.
