Positive Technologies (AI Summary)

CVSS v2.0

7.5

High

Base vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions: PPTP server versions prior to 1.1.4-b3

Description: The issue allows remote attackers to cause a denial of service. This is achieved by setting a length field to 0 or 1, which results in a negative value being used in a read operation, leading to a buffer overflow.

Recommendations: For versions prior to 1.1.4-b3, update to version 1.1.4-b3 or later to resolve the issue. As a temporary workaround, consider restricting access to the ctrlpacket.c module to minimize the risk of exploitation.
