Description John Helmert III gentoo-dev Security 2021-08-07 02:17:21 UTC
CVE-2021-3580:

A flaw was found in the way nettle's RSA decryption functions handled specially crafted ciphertext. An attacker could use this flaw to provide a manipulated ciphertext leading to application crash and denial of service.


The patches that RedHat neglected to reference in the CVE are at URL and both
appear to be released with 3.7.3:

https://git.lysator.liu.se/nettle/nettle/-/commit/0ad0b5df315665250dfdaa4a1e087f4799edaefe
https://git.lysator.liu.se/nettle/nettle/-/commit/485b5e2820a057e873b1ba812fdb39cae4adf98c

So, please stabilize 3.7.3.
