Doc Text:	A vulnerability was found in archive/zip of the Go standard library. Applications written in Go can panic or potentially exhaust system memory when parsing malformed ZIP files. An attacker capable of submitting a crafted ZIP file to a Go application using archive/zip to process that file could cause a denial of service via memory exhaustion or panic. This particular flaw is an incomplete fix for a previous flaw.	Story Points:	---

Description Guilherme de Almeida Suckevicz 2021-09-20 18:34:44 UTC

The fix for CVE-2021-33196 can be bypassed by crafted inputs. As a result, the NewReader and OpenReader functions in archive/zip can still cause a panic or an unrecoverable fatal error when reading an archive that claims to contain a large number of files, regardless of its actual size.
