CVE-2016-6129 (opens in a new tab)How to fix?
Upgrade Debian:13 libtomcrypt to version 1.17-8 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libtomcrypt package and not the libtomcrypt package as distributed by Debian.
See How to fix? for Debian:13 relevant fixed versions and status.
The rsa_verify_hash_ex function in rsa_verify_hash.c in LibTomCrypt, as used in OP-TEE before 2.2.0, does not validate that the message length is equal to the ASN.1 encoded data length, which makes it easier for remote attackers to forge RSA signatures or public certificates by leveraging a Bleichenbacher signature forgery attack.
