CVE-2022-2879: Unbounded memory consumption when reading headers in archive/tar

First published: Tue Oct 04 2022(Updated: )

A flaw was found in the golang package, where Reader.Read does not set a limit on the maximum size of file headers. After fixing, Reader.Read limits the maximum size of header blocks to 1 MiB. This flaw allows a maliciously crafted archive to cause Read to allocate unbounded amounts of memory, potentially causing resource exhaustion or panic.
