Debian Bugs : 321927 343680
The unzip update in DSA 903 contained a regression so that symbolic
links that are resolved later in a zip archive aren't supported
anymore. This update corrects this behaviour. For completeness,
below plese find the original advisory text:
Imran Ghory discovered a race condition in the permissions setting
code in unzip. When decompressing a file in a directory an
attacker has access to, unzip could be tricked to set the file
permissions to a different file the user has permissions to.
