Fix CVE-2017-7467, a remote exploitalbe out of bound access
|
|
|
|
This fixes an out of bounds data access that can lead to a
|
|
remotely exploitable code execution.
|
|
|
|
This issue was found by Solar Designer of Openwall during a
|
|
security audit of the Virtuozzo 7 product, which contains
|
|
derived downstream code in its prl-vzvncserver component.
|
|
The corresponding Virtuozzo 7 fix is:

|
|
Openwall would like to thank the Virtuozzo company for
|
|
funding the effort.
