-Subject: [PATCH] gmp: Fix buffer overflow with very small RSA keys
-
-Because `keylen` is unsigned the subtraction results in an integer
-underflow if the key length is < 11 bytes.
-
-This is only a problem when verifying signatures with a public key (for
-private keys the plugin enforces a minimum modulus length) and to do so
-we usually only use trusted keys.  However, the x509 plugin actually
-calls issued_by() on a parsed certificate to check if it is self-signed,
-which is the reason this issue was found by OSS-Fuzz in the first place.
-So, unfortunately, this can be triggered by sending an invalid client
-cert to a peer.
-
-Fixes: 5955db5b124a ("gmp: Don't parse PKCS1 v1.5 RSA signatures to verify them")
-Fixes: CVE-2018-17540
