EUVDB-ID: #VU23452
Risk: Low
CVSSv3.1: 2.2 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-48570,CVE-2019-14318
CWE-ID:
CWE-385 - Covert Timing Channel
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to scalar multiplication in ecp.cpp (prime field curves, small leakage) and algebra.cpp (binary field curves, large leakage) is not constant time and leaks the bit length of the scalar among other information within the timing side channel in ECDSA signature generation. A local user with ability to measure the duration of hundreds to thousands of signing operations can compute the private key used.
MitigationUpdate the affected package to version 8.2.0-2.
