Bug(s): #70227

Synopsis

zip contains a buffer overflow when creating a ZIP archive of files with very long path names. This could lead to the execution of arbitrary code.

Background

zip is a compression and file packaging utility.

Affected Packages

Package: app-arch/zip
Vulnerable: <= 2.3-r3
Unaffected: >= 2.3-r4

Workaround

There is no known workaround at this time.

Resolution

All zip users should upgrade to the latest version:
