Name of the Vulnerable Software and Affected Versions SecureCRT versions prior to 8.7.2

Description The issue allows remote attackers to execute arbitrary code via an Integer Overflow and a Buffer Overflow. This occurs because a banner can trigger a line number to CSI functions that exceeds INT MAX, leading to memory corruption in CSI functions.

Recommendations For SecureCRT versions prior to 8.7.2, update to version 8.7.2 or later to resolve the issue. As a temporary workaround, consider restricting access to CSI functions until a patch is available.
