CVE-2021-20491

Name of the Vulnerable Software and Affected Versions: IBM Spectrum Protect Server versions 7.1 through 8.1

Description: The issue is caused by improper bounds checking during the parsing of commands, leading to a stack-based buffer overflow. An authorized administrator could overflow a buffer and cause the server to crash by issuing a command with an improper parameter.

Recommendations: For IBM Spectrum Protect Server versions 7.1 through 8.1, consider restricting access to authorized administrators and limiting the use of commands that could trigger the buffer overflow until a fix is available. As a temporary workaround, carefully review and validate all command parameters to prevent improper input.
