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

Date: Sat, 14 Feb 2015 15:39:19 +0100

Package: ptlib
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:
http://www.kb.cert.org/vuls/id/695940
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 configure script picks the glibc regex code, so this doesn't affect
the Debian binary packages. 

It would still be useful to report this upstream, so that they update
the local regex code (it could be that the local one is used when
building with a libc other than glibc)

Cheers,

I have committed the patch upstream, thank you:

and
https://sourceforge.net/p/opalvoip/code/33382/

Shouldn't we close this bug in debian?

You can either close it rightway and once the new upstream release
with above changes hits unstable.
