CVE-2006-0058 cpe://redhat:enterprise_linux:3 cpe://redhat:enterprise_linux:4 Red Hat Enterprise Linux 3 Red Hat Enterprise Linux 4 GnuPG is a utility for encrypting data and creating digital signatures. Tavis Ormandy discovered a bug in the way GnuPG verifies cryptographically signed data with detached signatures. It is possible for an attacker to construct a cryptographically signed message which could appear to come from a third party. When a victim processes a GnuPG message with a malformed detached signature, GnuPG ignores the malformed signature, processes and outputs the signed data, and exits with status 0, just as it would if the signature had been valid. In this case, GnuPG's exit status would not indicate that no signature verification had taken place. This issue would primarily be of concern when processing GnuPG results via an automated script. The Common Vulnerabilities and Exposures project assigned the name CVE-2006-0455 to this issue. Tavis Ormandy also discovered a bug in the way GnuPG verifies cryptographically signed data with inline signatures. It is possible for an attacker to inject unsigned data into a signed message in such a way that when a victim processes the message to recover the data, the unsigned data is output along with the signed data, giving the appearance of having been signed. This issue is mitigated in the GnuPG shipped with Red Hat Enterprise Linux as the --ignore-crc-error option must be passed to the gpg executable for this attack to be successful. The Common Vulnerabilities and Exposures project assigned the name CVE-2006-0049 to this issue.

A bug was found in Apache where an invalid Expect header sent to the server was returned to the user in an unescaped error message. This could allow an attacker to perform a cross-site scripting attack if a victim was tricked into connecting to a site and sending a carefully crafted Expect header. (CVE-2006-3918) While a web browser cannot be forced to send an arbitrary Expect header by a third-party attacker, it was recently discovered that certain versions of the Flash plugin can manipulate request headers. If users running such versions can be persuaded to load a web page with a malicious Flash applet, a cross-site scripting attack against the server may be possible. On Red Hat Enterprise Linux 3 and 4 systems, due to an unrelated issue in the handling of malformed Expect headers, the page produced by the cross-site scripting attack will only be returned after a timeout expires (2-5 minutes by default) if not first canceled by the user.

Henson of the OpenSSL core team and Open Network Security recently developed an ASN.1 test suite for NISCC (www.niscc.gov.uk) which uncovered denial of service vulnerabilities: * Certain public key types can take disproportionate amounts of time to process, leading to a denial of service. (CVE-2006-2940) * During parsing of certain invalid ASN.1 structures an error condition was mishandled. This can result in an infinite loop which consumed system memory (CVE-2006-2937). This issue does not affect the OpenSSL version distributed in Red Hat Enterprise Linux 2.1. These vulnerabilities can affect applications which use OpenSSL to parse ASN.1 data from untrusted sources, including SSL servers which enable client authentication and S/MIME applications. Users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. Note: After installing this update, users are advised to either restart all services that use OpenSSL or restart their system. Important Copyright 2006 Red Hat, Inc.

This package includes the core files necessary for both the OpenSSH client and server. Mark Dowd discovered a signal handler race condition in the OpenSSH sshd server. A remote attacker could possibly leverage this flaw to cause a denial of service (crash). (CVE-2006-5051) The OpenSSH project believes the likelihood of successful exploitation leading to arbitrary code execution appears remote. However, the Red Hat Security Response Team have not yet been able to verify this claim due to lack of upstream vulnerability information. We are therefore including a fix for this flaw and have rated it important security severity in the event our continued investigation finds this issue to be exploitable. Tavis Ormandy of the Google Security Team discovered a denial of service bug in the OpenSSH sshd server. A remote attacker can send a specially crafted SSH-1 request to the server causing sshd to consume a large quantity of CPU resources. (CVE-2006-4924) All users of openssh should upgrade to these updated packages, which contain backported patches that resolves these issues. Important Copyr
