Description Hanno Böck gentoo-dev 2015-04-15 00:35:55 UTC
This sounds rather serious:

I don't know how widespread the use of the mod_copy module is. There is no upstream release with the fix yet (and it's been a week since this was publicly fixed...), probably should be backported.
Comment 2 Ian Delaney (RETIRED) gentoo-dev 2015-05-27 05:45:06 UTC
This took hours. For starters

index 526ee3a..879dee2 100644

is not necessary in a patch for gentoo. Files mod_copy.c & 
doc/contrib/mod_copy.html it seems have been patched by other commits since the release of proftpd-1.3.5, added to portage (16 May 2014). Attempting backporting, they had to be completely re-based.  The file tests/t/lib/ProFTPD/Tests/Modules/ took as it came with the patch. 
Since they were made in different styles, the final sec patch comes in 2 patches.

~/cvsPortage/gentoo-x86/net-ftp/proftpd $ USE="ssl openssl"  ebuild proftpd-1.3.5-
r2.ebuild compile

This would now require fast track stabilising.

You need USE=copy as well: bug #550644

CVE-2015-3306 (
  The mod_copy module in ProFTPD 1.3.5 allows remote attackers to read and
  write to arbitrary files via the site cpfr and site cpto commands.
