Severity: Normal Title: Apache Portable Runtime, APR Utility Library: Execution of arbitrary code Date: September 09, 2009 Bugs: #280514 ID: 200909-03
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis ========
Multiple integer overflows in the Apache Portable Runtime and its Utility Library might allow for the remote execution of arbitrary code.
Background ==========
The Apache Portable Runtime (aka APR) provides a set of APIs for creating platform-independent applications. The Apache Portable Runtime Utility Library (aka APR-Util) provides an interface to functionality such as XML parsing, string matching and databases connections.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/apr < 1.3.8 >=3D 1.3.8 2 dev-libs/apr-util < 1.3.9 >=3D 1.3.9 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
Matt Lewis reported multiple Integer overflows in the apr_rmm_malloc(), apr_rmm_calloc(), and apr_rmm_realloc() functions in misc/apr_rmm.c of APR-Util and in memory/unix/apr_pools.c of APR, both occurring when aligning memory blocks.
Impact ======
A remote attacker could entice a user to connect to a malicious server with software that uses the APR or act as a malicious client to a server that uses the APR (such as Subversion or Apache servers), possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Apache Portable Runtime users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose =3Ddev-libs/apr-1.3.8
All APR Utility Library users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose =3Ddev-libs/apr-util-1.3.9
