Name of the Vulnerable Software and Affected Versions: ppp version 2.4.1

Description: The issue is caused by an integer underflow in the cbcp.c file of the pppd application, allowing remote attackers to cause a denial of service by crashing the daemon. This is achieved by sending a CBCP packet with an invalid length value, which causes the application to access an incorrect memory location.

Recommendations: For ppp version 2.4.1, update to a newer version that contains a fix for this issue to prevent remote attackers from crashing the daemon.
