The mapelf32exec function call in IRIX 6.5.20 through 6.5.24 allows local users to cause a denial of service (system crash) via a "corrupted binary."

Updated kernel packages are now available as part of ongoing support and maintenance of Red Hat Enterprise Linux version 2.1. This is the sixth regular update.

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

This is the sixth regular kernel update to Red Hat Enterprise Linux version 2.1. It updates a number of device drivers, and adds much improved SATA support.

This update includes fixes for several security issues :

Paul Starzetz of iSEC discovered various flaws in the ELF binary loader affecting kernels prior to 2.4.28. A local user could use these flaws to gain read access to executable-only binaries or possibly gain privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2004-1070, CVE-2004-1071, CVE-2004-1072, and CVE-2004-1073 to these 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. (CVE-2004-1068)

Stefan Esser discovered various flaws including buffer overflows in the smbfs driver affecting kernels before 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 need to have control of a connected smb server. (CVE-2004-0883, CVE-2004-0949)

Conectiva discovered flaws in certain USB drivers affecting kernels before 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)

The ext3 code in kernels before 2.4.26 did not properly initialize journal descriptor blocks. A privileged local user could read portions of kernel memory. (CVE-2004-0177)

The following drivers have also been updated :

* tg3 v3.10 * e1000 v5.3.19-k2 * e100 v3.0.27-k2 * megaraid * megaraid2 v2.10.8.2

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

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

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)
