Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been discovered in GnuPG and Libgcrypt, |
| 19 |
which may result in execution of arbitrary code, Denial of Service, or |
| 20 |
the disclosure of private keys. |
| 21 |

Background |
| 23 |
========== |
| 24 |
|

|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
An unauthenticated remote attacker may be able to execute arbitrary |
| 51 |
code with the privileges of the user running GnuPG, cause a Denial of |
| 52 |
Service condition, or bypass security restrictions. Additionally, a |
| 53 |
side-channel attack may allow a local attacker to recover a private |
| 54 |
key, please review "Flush+Reload: a High Resolution, Low Noise, L3 |
| 55 |
Cache Side-Channel Attack" in the References section for further |
| 56 |
details. |
