Subject: Henry Spencer regular expressions (regex) library contains a heap overflow vulnerability

Date: Sat, 14 Feb 2015 15:38:55 +0100

Package: efl
Severity: important
Tags: security patch

The security team received a report from the CERT Coordination Center that the 
Henry Spencer regular expressions (regex) library contains a heap overflow 
vulnerability. It looks like this package includes the affected code at that's 
the reason of this bug report.

The patch is available here:
http://gitweb.dragonflybsd.org/dragonfly.git/blobdiff/4d133046c59a851141519d03553a70e903b3eefc..2841837793bd095a82f477e9c370cfe6cfb3862c:/lib/libc/regex/regcomp.c

Please, can you confirm if the binary packages are affected? Are stable and 
testing affected?

More information, here:

https://guidovranken.wordpress.com/2015/02/04/full-disclosure-heap-overflow-in-h-spencers-regex-library-on-32-bit-systems/

A CVE id has been requested already and the report will be updated with it 
eventually.

Cheers, luciano

The regex code in libevil is only linked when building for Windows,
so closing the bug.

Albin, you could still forward this to upstream, so they get the regex
code updated anyway?
