Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two vulnerabilities have been reported in Boost, each one possibly |
| 19 |
resulting in a Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Boost is a set of C++ libraries, including the Boost.Regex library to |
| 25 |
process regular expressions. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Tavis Ormandy and Will Drewry from the Google Security Team reported a |
| 39 |
failed assertion in file regex/v4/perl_matcher_non_recursive.hpp |
| 40 |
(CVE-2008-0171) and a NULL pointer dereference in function |
| 41 |
get_repeat_type() file basic_regex_creator.hpp (CVE-2008-0172) when |
| 42 |
processing regular expressions. |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
A remote attacker could provide specially crafted regular expressions |
| 48 |
to an application using Boost, resulting in a crash. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All Boost users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=dev-libs/boost-1.34.1-r2" |
| 62 |
