CVE-2017-9526
5.9 · MEDIUMOverview
CVE-2017-9526 is a medium-severity vulnerability affecting gnupg libgcrypt. It was published on June 11, 2017 and has a CVSS 3.0 base score of 5.9 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 5.9, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
In Libgcrypt before 1.7.7, an attacker who learns the EdDSA session key (from side-channel observation during the signing process) can easily recover the long-term secret key. 1.7.7 makes a cipher/ecc-eddsa.c change to store this session key in secure memory, to ensure that constant-time point operations are used in the MPI library.
Remediation
Check the references section for vendor advisories and patches from gnupg. Update libgcrypt to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
