A vulnerability, which was classified as problematic, has been found in OpenSSL 0.9.8i (Network Encryption Software). This issue affects an unknown code block. The manipulation with an unknown input leads to a cryptographic issues vulnerability. Using CWE to declare the problem leads to CWE-310. Impacted is confidentiality. The summary by CVE is:

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."

The issue has been introduced in 09/15/2008. The weakness was published 03/05/2010 (Website). The advisory is shared at osvdb.org. The identification of this vulnerability is CVE-2010-0928 since 03/05/2010. The exploitation is known to be difficult. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 536 days. During that time the estimated underground price was around $5k-$25k.

Upgrading to version 0.9.8i eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at X-Force (56750).
