CVE-2015-8805 Open this link in a new tabHow to fix?
Upgrade Debian:9
nettle
to version 3.2-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nettle
package and not the nettle
package as distributed by Debian
.
See How to fix?
for Debian:9
relevant fixed versions and status.
The ecc_256_modq function in ecc-256.c in Nettle before 3.2 does not properly handle carry propagation and produces incorrect output in its implementation of the P-256 NIST elliptic curve, which allows attackers to have unspecified impact via unknown vectors, a different vulnerability than CVE-2015-8803.
