Descriptions

In archive/zip in Go before 1.16.8 and 1.17.x before 1.17.1, a crafted archive header (falsely designating that many files are present) can cause a NewReader or OpenReader panic. NOTE: this issue exists because of an incomplete fix for CVE-2021-33196.

En archive/zip en Go versiones anteriores a 1.16.8 y 1.17.x versiones anteriores a 1.17.1, un encabezado de archivo diseñada (designando falsamente que hay muchos archivos presentes) puede causar un pánico en NewReader o OpenReader. NOTA: este problema se presenta debido a una corrección incompleta de CVE-2021-33196

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.
