Description

Updated kernel packages that fix several security issues in Red Hat Enterprise Linux 3 are now available.

The Linux kernel handles the basic functions of the operating system.

This update includes fixes for several security issues :

A missing serialization flaw in unix_dgram_recvmsg was discovered that affects kernels prior to 2.4.28. A local user could potentially make use of a race condition in order to gain privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1068 to this issue.

Paul Starzetz of iSEC discovered various flaws in the ELF binary loader affecting kernels prior to 2.4.28. A local user could use thse flaws to gain read access to executable-only binaries or possibly gain privileges. (CVE-2004-1070, CVE-2004-1071, CVE-2004-1072, CVE-2004-1073)

A flaw when setting up TSS limits was discovered that affects AMD AMD64 and Intel EM64T architecture kernels prior to 2.4.23. A local user could use this flaw to cause a denial of service (crash) or possibly gain privileges. (CVE-2004-0812)

An integer overflow flaw was discovered in the ubsec_keysetup function in the Broadcom 5820 cryptonet driver. On systems using this driver, a local user could cause a denial of service (crash) or possibly gain elevated privileges. (CVE-2004-0619)

Stefan Esser discovered various flaws including buffer overflows in the smbfs driver affecting kernels prior to 2.4.28. A local user may be able to cause a denial of service (crash) or possibly gain privileges. In order to exploit these flaws the user would require control of a connected Samba server. (CVE-2004-0883, CVE-2004-0949)

SGI discovered a bug in the elf loader that affects kernels prior to 2.4.25 which could be triggered by a malformed binary. On architectures other than x86, a local user could create a malicious binary which could cause a denial of service (crash). (CVE-2004-0136)

Conectiva discovered flaws in certain USB drivers affecting kernels prior to 2.4.27 which used the copy_to_user function on uninitialized structures. These flaws could allow local users to read small amounts of kernel memory. (CVE-2004-0685)

All Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.
