Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
Multiple integer overflows in the Apache Portable Runtime and its |
| 20 |
Utility Library might allow for the remote execution of arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
The Apache Portable Runtime (aka APR) provides a set of APIs for |
| 26 |
creating platform-independent applications. The Apache Portable Runtime |
| 27 |
Utility Library (aka APR-Util) provides an interface to functionality |
| 28 |
such as XML parsing, string matching and databases connections. |

Description |
| 43 |
=========== |
| 44 |
|
| 45 |
Matt Lewis reported multiple Integer overflows in the apr_rmm_malloc(), |
| 46 |
apr_rmm_calloc(), and apr_rmm_realloc() functions in misc/apr_rmm.c of |
| 47 |
APR-Util and in memory/unix/apr_pools.c of APR, both occurring when |
| 48 |
aligning memory blocks. |
| 49 |
|
| 50 |
Impact |
| 51 |
====== |
| 52 |
|
| 53 |
A remote attacker could entice a user to connect to a malicious server |
| 54 |
with software that uses the APR or act as a malicious client to a |
| 55 |
server that uses the APR (such as Subversion or Apache servers), |
| 56 |
possibly resulting in the execution of arbitrary code with the |
| 57 |
privileges of the user running the application. |
| 58 |
|
| 59 |
Workaround |
| 60 |
========== |
| 61 |
|
| 62 |
There is no known workaround at this time. |
| 63 |
|
| 64 |
Resolution |
| 65 |
========== |
| 66 |
|
| 67 |
All Apache Portable Runtime users should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot --verbose =dev-libs/apr-1.3.8 |
| 71 |
|
| 72 |
All APR Utility Library users should upgrade to the latest version: |
| 73 |
|
| 74 |
# emerge --sync |
| 75 |
# emerge --ask --oneshot --verbose =dev-libs/apr-util-1.3.9 |
| 76 |
