Description
This security bulletin contains information about 1 security vulnerability.
1) Privilege escalation (CVE-ID: N/A)
The vulnerability allows a local attacker to gain elevated privileges on the target system.The weakness exists due to boundary error in a kernel driver, PGPwded.sys, in Symantec Encryption Desktop when processing input/output control requests (IOCTLs). A local attacker can send specially crafted input/output control requests (IOCTLs), trigger memory corruption, attain arbitrary hard disk read and write access at sector level, subsequently infect the target, gain low level persistence (MBR/VBR) and execute arbitrary code in the context of the built-in SYSTEM user account, without requiring a reboot.
Successful exploitation of the vulnerability may result in system compromise.
