4Mhz · B64Dec · CVE-2020-37124
**Name of the Vulnerable Software and Affected Versions**
B64dec version 1.1.2
**Description**
A buffer overflow allows attackers to execute arbitrary code by overwriting the Structured Exception Handler (SEH), which is a mechanism for handling software exceptions, using crafted input. This can be achieved by employing an egg hunter technique—a small piece of code used to find a larger payload in memory—and a carefully constructed payload during the base64 decoding process.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
