Gentoo Linux Security Advisory

Title: Apache Portable Runtime, APR Utility Library: Execution of arbitrary code (GLSA 200909-03)
Severity: normal
Exploitable: remote
Date: September 09, 2009
Bug(s): #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: dev-libs/apr
Vulnerable: < 1.3.8
Unaffected: >= 1.3.8
Architectures: All supported architectures

Package: dev-libs/apr-util
Vulnerable: < 1.3.9
Unaffected: >= 1.3.9
Architectures: All 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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/apr-1.3.8"

All APR Utility Library users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/apr-util-1.3.9"
