This update has been rated as having moderate security impact by the Red Hat Security Response Team. apr-util is a utility library used with the Apache Portable Runtime (APR). It aims to provide a free library of C data structures and routines. This library contains additional utility interfaces for APR; including support for XML, LDAP, database interfaces, URI parsing, and more. An off-by-one overflow flaw was found in the way apr-util processed a variable list of arguments. An attacker could provide a specially crafted string as input for the formatted output conversion routine, which could, on big-endian platforms, potentially lead to the disclosure of sensitive information or a denial of service (application crash). (CVE-2009-1956) Note: The CVE-2009-1956 flaw only affects big-endian platforms, such as the IBM S/390 and PowerPC. It does not affect users using the apr-util package on little-endian platforms, due to their different organization of byte ordering used to represent particular data. A denial of service flaw was found in the apr-util Extensible Markup Language (XML) parser. A remote attacker could create a specially crafted XML document that would cause excessive memory consumption when processed by the XML decoding engine. (CVE-2009-1955) A heap-based underwrite flaw was found in the way apr-util created compiled forms of particular search patterns. An attacker could formulate a specially crafted search keyword, that would overwrite arbitrary heap memory locations when processed by the pattern preparation engine. (CVE-2009-0023) All apr-util users should upgrade to these updated packages, which contain backported patches to correct these issues. Applications using the Apache Portable Runtime library, such as httpd, must be restarted for this update to take effect. last seen 2020-06-01 modified 2020-06-02 plugin id 43758 published 2010-01-06 reporter This script is Copyright (C) 2010-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/43758 title CentOS 5 : apr-util (CESA-2009:1107) NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_EB9212F7526B11DEBBF2001B77D09812.NASL description Secunia reports : Some vulnerabilities have been reported in APR-util, which can be exploited by malicious users and malicious people to cause a DoS (Denial of Service).

An attacker could cause a denial of service via application crash in Apache using a crafted SVNMasterURI directive, .htaccess file, or when using mod_apreq2. Applications using libapreq2 are also affected. (CVE-2009-0023) It was discovered that the XML parser did not properly handle entity expansion. A remote attacker could cause a denial of service via memory resource consumption by sending a crafted request to an Apache server configured to use mod_dav or mod_dav_svn. (CVE-2009-1955) C. Michael Pilato discovered an off-by-one buffer overflow in apr-util when formatting certain strings. For big-endian machines (powerpc, hppa and sparc in Ubuntu), a remote attacker could cause a denial of service or information disclosure leak. All other architectures for Ubuntu are not considered to be at risk. (CVE-2009-1956).

The httpd package shipped with Red Hat Enterprise Linux 3 contains an embedded copy of the Apache Portable Runtime (APR) utility library, a free library of C data structures and routines, which includes interfaces to support XML parsing, LDAP connections, database interfaces, URI parsing, and more. An off-by-one overflow flaw was found in the way apr-util processed a variable list of arguments. An attacker could provide a specially crafted string as input for the formatted output conversion routine, which could, on big-endian platforms, potentially lead to the disclosure of sensitive information or a denial of service (application crash). (CVE-2009-1956) Note: The CVE-2009-1956 flaw only affects big-endian platforms, such as the IBM S/390 and PowerPC. It does not affect users using the httpd package on little-endian platforms, due to their different organization of byte ordering used to represent particular data. A denial of service flaw was found in the apr-util Extensible Markup Language (XML) parser. A remote attacker could create a specially crafted XML document that would cause excessive memory consumption when processed by the XML decoding engine. (CVE-2009-1955) A heap-based underwrite flaw was found in the way apr-util created compiled forms of particular search patterns. An attacker could formulate a specially crafted search keyword, that would overwrite arbitrary heap memory locations when processed by the pattern preparation engine. (CVE-2009-0023) All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect. last seen 2020-06-01 modified 2020-06-02 plugin id 39438 published 2009-06-18 reporter This script is Copyright (C) 2009-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/39438 title CentOS 3 : httpd (CESA-2009:1108) NASL family Web Servers NASL id APACHE_2_2_12.NASL description According to its banner, the version of Apache 2.2.x. running on the remote host is prior to 2.2.12.
