NVD Description

Note: Versions mentioned in the description apply only to the upstream gnupg2-smime package and not the gnupg2-smime package as distributed by RHEL.

In GnuPG before 2.5.17, a crafted CMS (S/MIME) EnvelopedData message carrying an oversized wrapped session key can cause a stack-based buffer overflow in gpg-agent during PKDECRYPT--kem=CMS handling. This can easily be leveraged for denial of service; however, there is also memory corruption that could lead to remote code execution.
