Vulnerability in Gaisler Leon3 Soc
CVE-2010-0928
OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain signature calculations, and does not verify the signature before providing it to a caller, which makes it easier for physically proximate attackers to determine the private key via a modified supply voltage for the microprocessor, related to a "fault-based attack."
Vulnerability class: POODLE (CVE-2014-3566)
Published · last modified .
CVSS v2 metric
CVSS v2 base score 4.0 (Medium). Vector: AV:L/AC:H/Au:N/C:C/I:N/A:N. This CVE predates CVSS v3 and has no v3 score from NVD.
EPSS exploit prediction
EPSS: 0.005 (42.9th percentile), scored .
Very low probability of exploitation in the next 30 days; routine patching cadence is appropriate. 43rd percentile — 42.9% of CVEs in the catalogue have a lower EPSS than this one. How to read EPSS.
