<impact type="normal">
|
|
<p>An unauthenticated remote attacker may be able to execute arbitrary code
|
|
with the privileges of the user running GnuPG, cause a Denial of Service
|
|
condition, or bypass security restrictions. Additionally, a side-channel
|
|
attack may allow a local attacker to recover a private key, please review
|
|
“Flush+Reload: a High Resolution, Low Noise, L3 Cache Side-Channel
|
|
Attack” in the References section for further details.
