Ubuntu 4.10 / 5.10 : linux-source-2.6.8.1/-2.6.10/-2.6.12 vulnerabilities (USN-219-1)

Medium Nessus Plugin ID 65105

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Al Viro discovered a race condition in the /proc file handler of network devices. A local attacker could exploit this by opening any file in /proc/sys/net/ipv4/conf/<interface>/ and waiting until that interface was shut down. Under certain circumstances this could lead to a kernel crash or even arbitrary code execution with full kernel privileges. (CVE-2005-2709)

Tetsuo Handa discovered a local Denial of Service vulnerability in the udp_v6_get_port() function. On computers which use IPv6, a local attacker could exploit this to trigger an infinite loop in the kernel.
(CVE-2005-2973)

Harald Welte discovered a Denial of Service vulnerability in the USB devio driver. A local attacker could exploit this by sending an 'USB Request Block' (URB) and terminating the sending process before the arrival of the answer, which left an invalid pointer and caused a kernel crash. (CVE-2005-3055)

Pavel Roskin discovered an information leak in the Orinoco wireless card driver. When increasing the buffer length for storing data, the buffer was not padded with zeros, which exposed a random part of the system memory to the user. (CVE-2005-3180)

A resource leak has been discovered in the handling of POSIX timers in the exec() function. This could be exploited to a Denial of Service attack by a group of local users. This vulnerability only affects Ubuntu 4.10. (CVE-2005-3271)

Stephen Hemming discovered a weakness in the network bridge driver.
Packets which had already been dropped by the packet filter could poison the forwarding table, which could be exploited to make the bridge forward spoofed packages. This vulnerability only affects Ubuntu 4.10 and 5.04. (CVE-2005-3272)

David S. Miller discovered a buffer overflow in the rose_rt_ioctl() function. By calling the function with a large 'ngidis' argument, a local attacker could cause a kernel crash. This vulnerability only affects Ubuntu 4.10 and 5.04. (CVE-2005-3273)

Neil Horman discovered a race condition in the connection timer handling. This allowed a local attacker to set up an expiration handler which modified the connection list while the list still being traversed, which could result in a kernel crash. This vulnerability only affects multiprocessor (SMP) systems. (CVE-2005-3274)

Patrick McHardy noticed a logic error in the network address translation (NAT) connection tracker. A remote attacker could exploit this by causing two packets for the same protocol to be NATed at the same time, which resulted in a kernel crash. (CVE-2005-3275)

Paolo Giarrusso discovered an information leak in the sys_get_thread_area(). The returned structure was not properly cleared, which exposed a small amount of kernel memory to userspace programs. This could possibly expose confidential data.
(CVE-2005-3276).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
