-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: apache,apache2 Announcement ID: SUSE-SA:2006:043 Date: Fri, 28 Jul 2006 17:00:00 +0000 Affected Products: SLE SDK 10 SUSE LINUX 10.1 SUSE LINUX 10.0 SUSE LINUX 9.3 SUSE LINUX 9.2 SUSE SLES 10 SUSE SLES 9 Vulnerability Type: remote denial of service Severity (1-10): 6 SUSE Default Package: yes Cross-References: CVE-2005-3352, CVE-2006-3747 Content of This Advisory: 1) Security Vulnerability Resolved: Apache off by one security problem Problem Description 2) Solution or Work-Around 3) Special Instructions and Notes 4) Package Location and Checksums 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion The following security problem was fixed in the Apache and Apache 2 web servers: mod_rewrite: Fix an off-by-one security problem in the ldap scheme handling. For some RewriteRules this could lead to a pointer being written out of bounds. Depending on stack alignment this could be used to potentially execute code. The mod_rewrite module is not enabled per default in our packages. This problem is tracked by the Mitre CVE ID CVE-2006-3747. A more detailed description of this problem is available in: http://www.apache.org/dist/httpd/Announcement2.0.html For SUSE Linux 10.0, 10.1 and SUSE Linux Enterprise 10 additionally a old bug was fixed that we missed to forward port to the Apache 2.2 packages: mod_imap: Fixes a cross-site-scripting bug in the imagemap module. This issue is tracked by the Mitre CVE ID CVE-2005-3352. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please close and restart all running instances of Apache after the update. 4) Package Location and Checksums The preferred method for installing security updates is to use the YaST Online Update (YOU) tool. YOU detects which updates are required and automatically performs the necessary steps to verify and install them. Alternatively, download the update packages for your distribution manually and verify their integrity by the methods listed in Section 6 of this announcement. Then install the packages using the command rpm -Fhv <file.rpm> to apply the update, replacing <file.rpm> with the filename of the downloaded RPM package. x86 Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/apache2-... 124342d5311b318586d91d12117bdd2a ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/apache2-... 4a73ae89777943f4127743f817f0a0a5 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/apache2-... 1905af7f606986f1818ebed5bd3382d5 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/apa... adf6c8665b9f0f36c6a7720a8f1bfad1 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/apa... 1cbcec6896dc46504140177b48ca014d ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/apa... f721e397c518cc6160886a1296e5a109 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/apac... e6ae2ee1353c1f1c31c0595b60d18137 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/apac... cb02c5f97671d2ab0a64215ed9987c2f ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/apac... b8872991cf54d99659e60d860d0c44e8 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/apac... 9365d403839e7c0740aae1e2f1b6cdfc ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/apac... 97d506d68996f80ffaaaa6494a127f7c ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/apac... f649e8eb98d43d6a44231f0c7453c9b2 Power PC Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/apache2-2... 133b02c7a3a52a2bf144ece351ba00a1 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/apache2-p... 099056b7a0f634ff1daf583ce2163839 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/apache2-w... a22ae78408cedfea6d66362509d3c721 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/apac... 16a119e6dab8e972a992ef37bd9973aa ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/apac... fcb8c3ca92f1b9a39791f51aad5b8907 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/apac... 0f5dff953aea37964958bc0ed8932412 x86-64 Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/apache... 3ab36db089d7f3d60a7114820970afdd ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/apache... b7e9bc09fe9684292acf0e7ed0218b14 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/apache... b6b1ab1c03073f7f2acc07a0231ea532 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/a... 17c4bdc7577446bf45335ba58ebb3513 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/a... d55a93a86ae6b5bf037ee336d4307133 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/a... e64fc86d3337913db0c22ffde3519a36 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/ap... d4996884e49ef11d27c97340efb6f079 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/ap... 5b599e78e59c7b59dc199777fe2c4eea ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/ap... 09f0f1dc18761a8a902f2dc5ab166883 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/ap... 595101ab05dfe5117ddab1d1f1463a28 ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/ap... 112fe5dd14b66a4fbb82c3c5178bef69 ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/ap... 7c07b8b400e6ed13a4707c3ebe1eed3a Sources: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/src/apache2-2... 493d11cc099e975bc0974611cf936816 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/apac... b83da64c6ad0b76d7a3a8bf909d61d39 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/apach... 5d4c85c7f60ea5c73df0fba7d92bec35 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/apach... 2c4e95c0ebe9bee49dec733cbdeb42d3 Our maintenance customers are notified individually.

The authenticity and integrity of a SUSE security announcement is guaranteed by a cryptographic signature in each announcement. All SUSE security announcements are published with a valid signature. To verify the signature of the announcement, save it as text into a file and run the command gpg --verify <file> replacing <file> with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made <DATE> using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team <security@suse.de>" where <DATE> is replaced by the date the document was signed. If the security team's key is not contained in your key ring, you can import it from the first installation CD. To import the key, use the command gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc - Package authenticity verification: SUSE update packages are available on many mirror FTP servers all over the world. While this service is considered valuable and important to the free and open source software community, the authenticity and the integrity of a package needs to be verified to ensure that it has not been tampered with. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or RPM package: 1) Using the internal gpg signatures of the rpm package 2) MD5 checksums as provided in this announcement 1) The internal rpm package signatures provide an easy way to verify the authenticity of an RPM package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, replacing <file.rpm> with the filename of the RPM package downloaded. The package is unmodified if it contains a valid signature from build@suse.de with the key ID 9C800ACA. This key is automatically imported into the RPM database (on RPMv4-based distributions) and the gpg key ring of 'root' during installation. You can also find it on the first installation CD and at the end of this announcement. 2) If you need an alternative means of verification, use the md5sum command to verify the authenticity of the packages. Execute the command md5sum <filename.rpm> after you downloaded the file from a SUSE FTP server or its mirrors. Then compare the resulting md5sum with the one that is listed in the SUSE security announcement. Because the announcement containing the checksums is cryptographically signed (by security@suse.de), the checksums show proof of the authenticity of the package if the signature of the announcement is valid. Note that the md5 sums published in the SUSE Security Announcements are valid for the respective packages only. Newer versions of these packages cannot be verified. - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-subscribe@suse.com>. suse-security-announce@suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-announce-subscribe@suse.com>.
