NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2005-283.NASL description Updated kernel packages are now available as part of ongoing support and maintenance of Red Hat Enterprise Linux version 2.1. This is the seventh regular update. This security advisory has been rated as having important security impact by the Red Hat Security Response Team. The Linux kernel handles the basic functions of the operating system. This is the seventh regular kernel update to Red Hat Enterprise Linux 2.1 The following security updates were made : A flaw in fragment queuing was discovered that affected the Linux 2.4 and Linux 2.6 kernel netfilter subsystem. On systems configured to filter or process network packets (for example those configured to do 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 in place on the target system to be able to craft the right fragmented packets. (CVE-2005-0449) 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 bluetooth driver system. On system where the bluetooth modules are loaded, a local user could use this flaw to gain elevated (root) privileges. (CVE-2005-0750) 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) Please note that this update contains an unpatched kernel module called bcm5820_old for backwards compatibility which is still vulnerable to CVE-2004-0619. The following device drivers have been updated to new versions : mptfusion: 2.05.16 -> 2.05.16.02 bcm5820: 1.17 -> 1.81 cciss: 2.4.52 -> 2.4.54 qla2x00: 6.04.01 -> 7.01.01 There were many bug fixes in various parts of the kernel. The ongoing effort to resolve these problems has resulted in a marked improvement in the reliability and scalability of Red Hat Enterprise Linux 2.1. Bug fixes include: - Fixes an incorrect and ever-changing physical_id field in /proc/cpuinfo. - Now recognizes a particular e1000 device (PCI ID 8086:1014) - Fixes a panic in disk quota code - Fixes a bug in which msync(...MS_SYNC) returns before the data is written to disk - Adds new devices to the SCSI scan list so they can be initialized and handled properly: LSI ProFibre 4000R, HP HSV200/210, HP MSA, STK OPENstorage D178. - Fixes a potential format overflow in /proc/partitions - Restores module parameters to the e100 driver for compatibility with existing customer scripts. - Fixes a bug in which cat last seen 2020-06-01 modified 2020-06-02 plugin id 18161 published 2005-04-29 reporter This script is Copyright (C) 2005-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/18161 title RHEL 2.1 : kernel (RHSA-2005:283) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2004-549.NASL 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. last seen 2020-06-01 modified 2020-06-02 plugin id 15944 published 2004-12-13 reporter This script is Copyright (C) 2004-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/15944 title RHEL 3 : kernel (RHSA-2004:549)
