Description Agostino Sarubbo gentoo-dev 2013-08-01 08:53:43 UTC
From ${URL} :

The Perl module Data::UUID from CPAN is vulnerable to symlink attacks.
 This is a widely used Perl module for generating UUIDs.

Details are in the bug report on github:
https://github.com/rjbs/Data-UUID/issues/5

I believe all released versions are affected - I have confirmed the
issue against 1.219.

Regarding affected distributions, note that Debian and Fedora do not
ship Data::UUID from CPAN - they use OSSP's uuid.  However, at least
Arch and Gentoo seem to ship the CPAN version.


@maintainer(s): after the bump, in case we need to stabilize the package, please say explicitly if it is ready for the stabilization or not.

I doubt that Data::UUID and ossp-uuid[perl] are interchangeable. 

Masking is also not an option yet since there is a chain of dependencies.

No patch has materialized.

No news from upstream.
Comment 3 Aaron Bauman Gentoo Infrastructure gentoo-dev Security 2018-04-09 00:23:18 UTC
This is protected against by fs.protected_symlinks which is on by default in gentoo-sources that is security supported.
