Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Numerous security issues have been discovered in Midnight Commander, |
| 38 |
including several buffer overflow vulnerabilities, multiple |
| 39 |
vulnerabilities in the handling of temporary file and directory |
| 40 |
creation, and multiple format string vulnerabilities. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
The buffer overflows and format string vulnerabilites may allow |
| 46 |
attackers to cause a denial of service or execute arbitrary code with |
| 47 |
permissions of the user running MC. The insecure creation of temporary |
| 48 |
files and directories could lead to a privilege escalation, including |
| 49 |
root privileges, for a local attacker. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. All users are advised to |
| 55 |
upgrade to version 4.6.0-r7 or higher of Midnight Commander. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All Midnight Commander users should upgrade to the latest stable |
| 61 |
version: |
| 62 |
|
| 63 |
# emerge sync |
| 64 |
|
| 65 |
# emerge -pv ">=app-misc/mc-4.6.0-r7 |
| 66 |
# emerge ">=app-misc/mc-4.6.0-r7" |
| 67 |
