Details

Description: PCRE 8.37 contains multiple security vulnerabilities (over half a dozen buffer overflows and reference offset bugs):
http://vcs.pcre.org/pcre/code/trunk/ChangeLog

At least one of those vulnerabilites has been assigned CVE-2015-3210, where it is also claimed that this can be used for remote code execution:
http://www.securitytracker.com/id/1032453

Although upstream has not yet released a new version of PCRE, they have fixed these vulnerabilities in their SVN:
https://bugs.exim.org/show_bug.cgi?id=1636#c1

I therefore propose that the SVN version of PCRE be shipped until upstream releases PCRE 8.38.


Additional info:
* package version(s): PCRE 8.33-8.37

Steps to reproduce:
Ask Wen Guanxing if you really need a working exploit.
This task depends upon

A version with patches is in testing. Could you confirm that's ok?

Hmmm, the download from mirror.rit.edu gives me a 404 although I had started (but then cancelled again) the download using my browser a few minutes ago. o_O

I'll quickly build the package myself (using GCC 5.1 and with a grsec kernel) and give you a feedback.

So far, no problems experienced, neither with your version nor with mine.

//EDIT: By the way, lib32-pcre would of course also need to be fixed.

Could you please also assign this bug to Florian Pritz (bluewind), as he is the maintainer of the lib32-pcre package?

I got access to multilib. That's now ok.
