RHSA-2003_368
Vulnerability from csaf_redhat - Published: 2003-12-19 18:10 - Updated: 2024-11-21 22:52Summary
Red Hat Security Advisory: Updated IA64 kernel packages address security vulnerabilities, bugfixes
Notes
Topic
Updated kernel packages that address several security vulnerabilites, fix a
number of bugs, and update various drivers are now available.
Details
The Linux kernel handles the basic functions of the operating system.
A flaw in bounds checking in the do_brk() function in the Linux kernel
versions 2.4.22 and previous can allow a local attacker to gain root
privileges. This issue is known to be exploitable; an exploit (for x86
architectures) has been seen in the wild that takes advantage of this
vulnerability. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0961 to this issue.
The execve system call in Linux 2.4.x records the file descriptor of the
executable process in the file table of the calling process, which allows
local users to gain read access to restricted file descriptors. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0476 to this issue.
A hangcheck timer (which is used to detect system hangs or pauses) has been
added.
In addition, a number of drivers have been updated:
- e1000 5.2.20-k1
- cmpci 5.64
- aic7xxx 6.2.36
- aic79xx 1.3.10
- ips 6.10.52
- cciss 2.4.50
- fusion 2.05.05+
All users of IA64 systems should upgrade to these errata packages, which
contain patches to the 2.4.18 kernel addressing these issues.

Vulnerability from csaf_redhat - Published: 2003-12-19 18:10 - Updated: 2025-11-21 17:26Summary
Red Hat Security Advisory: Updated IA64 kernel packages address security vulnerabilities, bugfixes
Notes
Topic
Updated kernel packages that address several security vulnerabilites, fix a
number of bugs, and update various drivers are now available.
Details
The Linux kernel handles the basic functions of the operating system.
A flaw in bounds checking in the do_brk() function in the Linux kernel
versions 2.4.22 and previous can allow a local attacker to gain root
privileges. This issue is known to be exploitable; an exploit (for x86
architectures) has been seen in the wild that takes advantage of this
vulnerability. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0961 to this issue.
The execve system call in Linux 2.4.x records the file descriptor of the
executable process in the file table of the calling process, which allows
local users to gain read access to restricted file descriptors. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0476 to this issue.
A hangcheck timer (which is used to detect system hangs or pauses) has been
added.
In addition, a number of drivers have been updated:
- e1000 5.2.20-k1
- cmpci 5.64
- aic7xxx 6.2.36
- aic79xx 1.3.10
- ips 6.10.52
- cciss 2.4.50
- fusion 2.05.05+
All users of IA64 systems should upgrade to these errata packages, which
contain patches to the 2.4.18 kernel addressing these issues.

Vulnerability from csaf_redhat - Published: 2003-07-21 15:36 - Updated: 2024-11-21 22:48Summary
Red Hat Security Advisory: : : : Updated 2.4 kernel fixes vulnerabilities
Notes
Topic
Updated kernel packages are now available fixing several security
vulnerabilities.
[Updated 28 August 2003]
Added CAN-2003-0699 and CAN-2003-0700 to the list of security issues that
are fixed by this advisory (there are no changes to the packages themselves).
Details
The Linux kernel handles the basic functions of the operating system.
Several security issues have been discovered affecting the Linux kernel:
CAN-2003-0461: /proc/tty/driver/serial reveals the exact character counts
for serial links. This could be used by a local attacker to infer password
lengths and inter-keystroke timings during password entry.
CAN-2003-0462: Paul Starzetz discovered a file read race condition existing
in the execve() system call, which could cause a local crash.
CAN-2003-0464: A recent change in the RPC code set the reuse flag on
newly-created sockets. Olaf Kirch noticed that his could allow normal
users to bind to UDP ports used for services such as nfsd.
CAN-2003-0476: The execve system call in Linux 2.4.x records the file
descriptor of the executable process in the file table of the calling
process, allowing local users to gain read access to restricted file
descriptors.
CAN-2003-0501: The /proc filesystem in Linux allows local users to obtain
sensitive information by opening various entries in /proc/self before
executing a setuid program. This causes the program to fail to change the
ownership and permissions of already opened entries.
CAN-2003-0550: The STP protocol is known to have no security, which could
allow attackers to alter the bridge topology. STP is now turned off by
default.
CAN-2003-0551: STP input processing was lax in its length checking, which
could lead to a denial of service.
CAN-2003-0552: Jerry Kreuscher discovered that the Forwarding table could
be spoofed by sending forged packets with bogus source addresses the same
as the local host.
CAN-2003-0699: The C-Media PCI sound driver in kernel versions prior to
2.4.21 does not use the get_user function to access userspace, which
crosses security boundaries and may facilitate the exploitation of
vulnerabilities.
CAN-2003-0700: The C-Media PCI sound driver in kernel versions prior to
2.4.22 accesses userspace without using the get_user function, which is a
potential security hole (NOTE: this issue is distinct from that described
in CAN-2003-0699).
All users are advised to upgrade to these errata packages, which contain
backported security patches correcting these vulnerabilities.
Important:
If you use Red Hat Linux 7.1, you must have installed quota-3.06-9.71 from
RHSA-2003-187, and if you use Red Hat Linux 7.2 or 7.3, you must have
installed quota-3.06-9.7 from RHSA-2003-187.

Vulnerability from csaf_redhat - Published: 2003-07-21 15:36 - Updated: 2025-11-21 17:26Summary
Red Hat Security Advisory: : : : Updated 2.4 kernel fixes vulnerabilities
Notes
Topic
Updated kernel packages are now available fixing several security
vulnerabilities.
[Updated 28 August 2003]
Added CAN-2003-0699 and CAN-2003-0700 to the list of security issues that
are fixed by this advisory (there are no changes to the packages themselves).
Details
The Linux kernel handles the basic functions of the operating system.
Several security issues have been discovered affecting the Linux kernel:
CAN-2003-0461: /proc/tty/driver/serial reveals the exact character counts
for serial links. This could be used by a local attacker to infer password
lengths and inter-keystroke timings during password entry.
CAN-2003-0462: Paul Starzetz discovered a file read race condition existing
in the execve() system call, which could cause a local crash.
CAN-2003-0464: A recent change in the RPC code set the reuse flag on
newly-created sockets. Olaf Kirch noticed that his could allow normal
users to bind to UDP ports used for services such as nfsd.
CAN-2003-0476: The execve system call in Linux 2.4.x records the file
descriptor of the executable process in the file table of the calling
process, allowing local users to gain read access to restricted file
descriptors.
CAN-2003-0501: The /proc filesystem in Linux allows local users to obtain
sensitive information by opening various entries in /proc/self before
executing a setuid program. This causes the program to fail to change the
ownership and permissions of already opened entries.
CAN-2003-0550: The STP protocol is known to have no security, which could
allow attackers to alter the bridge topology. STP is now turned off by
default.
CAN-2003-0551: STP input processing was lax in its length checking, which
could lead to a denial of service.
CAN-2003-0552: Jerry Kreuscher discovered that the Forwarding table could
be spoofed by sending forged packets with bogus source addresses the same
as the local host.
CAN-2003-0699: The C-Media PCI sound driver in kernel versions prior to
2.4.21 does not use the get_user function to access userspace, which
crosses security boundaries and may facilitate the exploitation of
vulnerabilities.
CAN-2003-0700: The C-Media PCI sound driver in kernel versions prior to
2.4.22 accesses userspace without using the get_user function, which is a
potential security hole (NOTE: this issue is distinct from that described
in CAN-2003-0699).
All users are advised to upgrade to these errata packages, which contain
backported security patches correcting these vulnerabilities.
Important:
If you use Red Hat Linux 7.1, you must have installed quota-3.06-9.71 from
RHSA-2003-187, and if you use Red Hat Linux 7.2 or 7.3, you must have
installed quota-3.06-9.7 from RHSA-2003-187.
