Linux kernel ext3 information disclosure
| linux-ext3-info-disclosure (15867) |  Medium Risk |
Description:
Linux kernel could allow a local attacker to obtain sensitive information. Linux kernel leaks ext3 code, which could allow an attacker to obtain information, such as cryptographic keys.
Consequences:
Obtain Information
Remedy:
