Linux kernel security
There has been a surprising series of kernel security problems reported
over the last week. These include:
- The uselib() vulnerability disclosed
by Paul Starzetz. A locking mistake in an old and mostly unused
system call creates a race condition which can be exploited to change
protections on memory - and compromise the system. The exploit has
not been released, but Mr. Starzetz claims that the race is relatively
easy to exploit by first consuming large amounts of memory to force
the kernel to sleep in the right spot.
- Paul Starzetz also discovered a race
condition in the page fault handler which can only be exploited on
SMP systems. If two threads tried to expand the same downward-growing
memory segment at the same time, the result could be an exploitable
corruption of the page tables.
- The grsecurity team, frustrated at a seeming lack of interest in
security problems among the kernel developers, disclosed five vulnerabilities at once.
One of these is a denial-of-service problem where users could lock
more than the authorized amount of memory into physical RAM; as it
turns out, the kernel developers still are
not overly concerned about that problem. The other
vulnerabilities require root access (or at least access to physical
devices) to exploit; one of them is in a driver which does not compile
in 2.6.
Fixes for the first two vulnerabilities have been merged into the
pre-2.6.11 BitKeeper repository; the last set will be fixed as well, but
with less urgency. Fixes can also be found in the -ac tree and in the updated kernels being
issued by distributors.
One concern that has been raised by these disclosures is that the new
kernel development model, by encouraging such large changes between
releases, is allowing the creation of more security problems. While that
worry could yet prove to be justified, all of the vulnerabilities listed
above, with the exception of the RLIMIT_MEMLOCK denial of service
problem, are present in the 2.4 kernel as well. They were not introduced
or enabled by the new development model.
Another concern is more valid, however: the kernel development project does
not have an official security contact or process for handling security
problems. Developers who know how the kernel process works have no trouble
getting consideration for security-related problems and patches, but the
whole process looks far more opaque to the rest of the world. There is a
clear need for an easily-found contact for kernel security issues. Chris
Wright, who has done a fair amount of security-related kernel work, is pushing for improvements in this area, and,
most importantly, has volunteered to do much of the work. So chances are
this problem will not last much longer.

libgd2: buffer overflows in PNG handling

CAN-2004-0941
|
| Created: | October 29, 2004 |
Updated: | June 28, 2006 |
| Description: |
Several buffer overflows have been discovered in libgd's PNG handling
functions.
If an attacker tricked a user into loading a malicious PNG image, they
could leverage this into executing arbitrary code in the context of
the user opening image. Most importantly, this library is commonly
used in PHP. One possible target would be a PHP driven photo website
that lets users upload images. Therefore this vulnerability might lead
to privilege escalation to a web server's privileges.
Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and
earlier may allow remote attackers to execute arbitrary code via malformed
image files that trigger the overflows due to improper calls to the
gdMalloc function. |
