It created a temporary directory in an insecure way which allowed for the exploitation of a race condition to create or overwrite files the privileges of the user invoking groffer. Likewise, similar temporary file issues were fixed in the pic2graph and eqn2graph programs which now use mktemp to create temporary files, as discovered by Javier Fernandez-Sanguino Pena. The updated packages have been patched to correct this issue. https://mandriva.com/security/advisories?name=MDKSA-2006:037 Mozilla and Mozilla Firefox allow remote attackers to cause a denial of service (CPU consumption and delayed application startup) via a web site with a large title, which is recorded in history.dat but not processed efficiently during startup. (CVE-2005-4134) The Javascript interpreter (jsinterp.c) in Mozilla and Firefox before 1.5.1 does not properly dereference objects, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via unknown attack vectors related to garbage collection. (CVE-2006-0292) The XULDocument.persist function in Mozilla, Firefox before 1.5.0.1, and SeaMonkey before 1.0 does not validate the attribute name, which allows remote attackers to execute arbitrary Javascript by injecting RDF data into the user's localstore.rdf file. (CVE-2006-0296) Updated packages are patched to address these issues. https://mandriva.com/security/advisories?name=MDKSA-2006:036 Mozilla and Mozilla Firefox allow remote attackers to cause a denial of service (CPU consumption and delayed application startup) via a web site with a large title, which is recorded in history.dat but not processed efficiently during startup.

(CVE-2006-0296) Updated packages are patched to address these issues. https://mandriva.com/security/advisories?name=MDKSA-2006:035 A flaw in the PHP gd extension in versions prior to 4.4.1 could allow a remote attacker to bypass safe_mode and open_basedir restrictions via unknown attack vectors. The updated packages have been patched to correct this issue. https://mandriva.com/security/advisories?name=MDKSA-2006:034 A flaw was discovered in the scp local-to-local copy implementation where filenames that contain shell metacharacters or spaces are expanded twice, which could lead to the execution of arbitrary commands if a local user could be tricked into a scp'ing a specially crafted filename. The provided updates bump the OpenSSH version to the latest release version of 4.3p1. A number of differences exist, primarily dealing with PAM authentication over the version included in Corporate 3.0 and MNF2. In particular, the default sshd_config now only accepts protocol 2 connections and UsePAM is now disabled by default. On systems using alternate authentication methods (ie. LDAP) that use the PAM stack for authentication, you will need to enable UsePAM. Note that the default /etc/pam.d/sshd file has also been modified to use the pam_listfile.so module which will deny access to any users listed in /etc/ssh/denyusers (by default, this is only the root user). This is required to preserve the expected behaviour when using "PermitRootLogin without-password"; otherwise it would still be possible to obtain a login prompt and login without using keys. Mandriva Linux 10.1 and newer already have these changes in their shipped versions. There are new features in OpenSSH and users are encouraged to review the new sshd_config and ssh_config files when upgrading. https://mandriva.com/security/advisories?name=MDKSA-2006:033 OpenOffice.org 2.0 and earlier, when hyperlinks has been disabled, does not prevent the user from clicking the WWW-browser button in the Hyperlink dialog, which makes it easier for attackers to trick the user into bypassing intended security settings. Updated packages are patched to address this issue. https://mandriva.com/security/advisories?name=MDKSA-2006:032 Heap-based buffer overflow in Splash.cc in xpdf allows attackers to cause a denial of service and possibly execute arbitrary code via crafted splash images that produce certain values that exceed the width or height of the associated bitmap. The updated packages have been patched to correct this issue. https://mandriva.com/security/advisories?name=MDKSA-2006:031 Heap-based buffer overflow in Splash.cc in xpdf allows attackers to cause a denial of service and possibly execute arbitrary code via crafted splash images that produce certain values that exceed the width or height of the associated bitmap. Kdegraphics-kpdf uses a copy of the xpdf code and as such has the same issues. The updated packages have been patched to correct this issue. https://mandriva.com/security/advisories?name=MDKSA-2006:030 Heap-based buffer overflow in Splash.cc in xpdf allows attackers to cause a denial of service and possibly execute arbitrary code via crafted splash images that produce certain values that exceed the width or height of the associated bitmap. Poppler uses a copy of the xpdf code and as such has the same issues. The updated packages have been patched to correct this issue. https://mandriva.com/security/advisories?name=MDKSA-2006:029 Buffer overflow in Library of Assorted Spiffy Things (LibAST) 0.6.1 and earlier, as used in Eterm and possibly other software, allows local users to execute arbitrary code as the utmp user via a long -X argument. The updated packages have been patched to correct this issue.
