CVE-2022-30630: Stack exhaustion in Glob on certain paths in io/fs

Published Jul 12, 2022
·
Updated

A flaw was found in the golang standard library, io/fs. Calling Glob on a path that contains a large number of path separators can cause a panic issue due to stack exhaustion. This could allow an attacker to impact availability.

Other sources

Calling Glob on a path which contains a large number of path separators can cause a panic due to stack exhaustion.

— Red Hat

Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Glob in io/fs due to stack exhaustion. By sending a specially-crafted request using a path which contains a large number of path separators, a remote attacker could exploit this vulnerability to cause a panic.

— IBM

Uncontrolled recursion in Glob in io/fs before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a panic due to stack exhaustion via a path which contains a large number of path separators.
