6.8
Média
| Vetor | AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
libgcrypt versions prior to 1.7.8
Description
The issue is related to a cache side-channel attack that can lead to a complete break of RSA-1024 and potentially RSA-2048 with increased computation. This attack requires the ability to run arbitrary software on the hardware where the private RSA key is used, allowing a local attacker to compromise data confidentiality by fully recovering the RSA key using the left-to-right method for computing the sliding-window expansion.
Recommendations
For libgcrypt versions prior to 1.7.8, update to version 1.7.8 or later to resolve the issue.
