Updated krb5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

Kerberos is a networked authentication system that uses a trusted third party (a KDC) to authenticate clients and servers to each other.

A double-free flaw was found in the krb5_recvauth() routine which may be triggered by a remote unauthenticated attacker. Red Hat Enterprise Linux 4 contains checks within glibc that detect double-free flaws.
Therefore, on Red Hat Enterprise Linux 4 successful exploitation of this issue can only lead to a denial of service (KDC crash). The Common Vulnerabilities and Exposures project assigned the name CVE-2005-1689 to this issue.

Daniel Wachdorf discovered a single byte heap overflow in the krb5_unparse_name() function, part of krb5-libs. Sucessful exploitation of this flaw would lead to a denial of service (crash).
To trigger this flaw an attacker would need to have control of a kerberos realm that shares a cross-realm key with the target, making exploitation of this flaw unlikely. (CVE-2005-1175).

Daniel Wachdorf also discovered that in error conditions that may occur in response to correctly-formatted client requests, the Kerberos 5 KDC may attempt to free uninitialized memory. This could allow a remote attacker to cause a denial of service (KDC crash) (CVE-2005-1174).

Gael Delalleau discovered an information disclosure issue in the way some telnet clients handle messages from a server. An attacker could construct a malicious telnet server that collects information from the environment of any victim who connects to it using the Kerberos-aware telnet client (CVE-2005-0488).

The rcp protocol allows a server to instruct a client to write to arbitrary files outside of the current directory. This could potentially cause a security issue if a user uses the Kerberos-aware rcp to copy files from a malicious server (CVE-2004-0175).

All users of krb5 should update to these erratum packages, which contain backported patches to correct these issues. Red Hat would like to thank the MIT Kerberos Development Team for their responsible disclosure of these issues.

A small memory leak when defragmenting local packets was discovered that affected the Linux 2.6 kernel netfilter subsystem. A local user could send a large number of carefully crafted fragments leading to memory exhaustion (CVE-2005-0210)

A flaw was discovered in the Linux PPP driver. On systems allowing remote users to connect to a server using ppp, a remote client could cause a denial of service (system crash). (CVE-2005-0384)

A flaw was discovered in the ext2 file system code. When a new directory is created, the ext2 block written to disk is not initialized, which could lead to an information leak if a disk image is made available to unprivileged users. (CVE-2005-0400)

A flaw in fragment queuing was discovered that affected the Linux kernel netfilter subsystem. On systems configured to filter or process network packets (e.g. firewalling), a remote attacker could send a carefully crafted set of fragmented packets to a machine and cause a denial of service (system crash). In order to sucessfully exploit this flaw, the attacker would need to know or guess some aspects of the firewall ruleset on the target system. (CVE-2005-0449)

A number of flaws were found in the Linux 2.6 kernel. A local user could use these flaws to read kernel memory or cause a denial of service (crash). (CVE-2005-0529, CVE-2005-0530, CVE-2005-0531)

An integer overflow in sys_epoll_wait in eventpoll.c was discovered. A local user could use this flaw to overwrite low kernel memory. This memory is usually unused, not usually resulting in a security consequence. (CVE-2005-0736)

A flaw when freeing a pointer in load_elf_library was discovered. A local user could potentially use this flaw to cause a denial of service (crash). (CVE-2005-0749)

A flaw was discovered in the bluetooth driver system. On systems where the bluetooth modules are loaded, a local user could use this flaw to gain elevated (root) privileges. (CVE-2005-0750)

A race condition was discovered that affected the Radeon DRI driver. A local user who has DRI privileges on a Radeon graphics card may be able to use this flaw to gain root privileges. (CVE-2005-0767)

Multiple range checking flaws were discovered in the iso9660 file system handler. An attacker could create a malicious file system image which would cause a denial or service or potentially execute arbitrary code if mounted. (CVE-2005-0815)

A flaw was discovered when setting line discipline on a serial tty. A local user may be able to use this flaw to inject mouse movements or keystrokes when another user is logged in. (CVE-2005-0839)

Red Hat Enterprise Linux 4 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

Please note that

Updated exim packages that fix a security issue in PCRE and a free space computation on large file system bug are now available for Red Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Exim is a mail transport agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet.

An integer overflow flaw was found in PCRE, a Perl-compatible regular expression library included within Exim. A local user could create a maliciously crafted regular expression in such as way that they could gain the privileges of the 'exim' user. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-2491 to this issue. These erratum packages change Exim to use the system PCRE library instead of the internal one.

These packages also fix a minor flaw where the Exim Monitor was incorrectly computing free space on very large file systems.

Users should upgrade to these erratum packages and also ensure they have updated the system PCRE library, for which erratum packages are available separately in RHSA-2005:761

Updated mysql-server packages that fix several vulnerabilities are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

MySQL is a multi-user, multi-threaded SQL database server.

This update fixes several security risks in the MySQL server.

Stefano Di Paola discovered two bugs in the way MySQL handles user-defined functions. A user with the ability to create and execute a user defined function could potentially execute arbitrary code on the MySQL server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2005-0709 and CVE-2005-0710 to these issues.

Stefano Di Paola also discovered a bug in the way MySQL creates temporary tables. A local user could create a specially crafted symlink which could result in the MySQL server overwriting a file which it has write access to. The Common Vulnerabilities and Exposures project has assigned the name CVE-2005-0711 to this issue.

All users of the MySQL server are advised to upgrade to these updated packages, which contain fixes for these issues.
