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 | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
app-arch/zip | <= 2.3-r3 | >= 2.3-r4 | All supported architectures |
Description
zip does not check the resulting path length when doing recursive folder compression.
Impact
An attacker could exploit this by enticing another user or web application to create an archive including a specially-crafted path name, potentially resulting in the execution of arbitrary code with the permissions of the user running zip.
Workaround
There is no known workaround at this time.
Resolution
All zip users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/zip-2.3-r4"
