CVE-2023-45290

Name of the Vulnerable Software and Affected Versions Go versions prior to the fixed version

Description The issue is related to parsing multipart forms, where limits on the total size of the parsed form were not applied to the memory consumed while reading a single form line. This allows a maliciously crafted input containing very long lines to cause allocation of arbitrarily large amounts of memory, potentially leading to memory exhaustion. The ParseMultipartForm function now correctly limits the maximum size of form lines with the fix.

Recommendations For Go versions prior to the fixed version, consider updating to a version that includes the fix for the ParseMultipartForm function to correctly limit the maximum size of form lines. As a temporary workaround, consider restricting the use of the Request.ParseMultipartForm, Request.FormValue, Request.PostFormValue, or Request.FormFile functions to minimize the risk of exploitation. Avoid using these functions with untrusted input until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability, but updating to the latest version may help mitigate the risk.
