Another image problem, this time for Linux

Another image-based security hole has been found, sparking a flurry of patches from Linux vendors.

Exploitation in GdkPixBuf can be used to caused a denial of service or provide remote system access. There are several vulnerabilities here: one is a variant of the previous discovered Qt hole in bitmap images that can make an application run in an infinite loop.

A second occurs in the "pixbuf_create_from_xpm()" function when decoding XPM images. A specially crafted image can cause a buffer overflow. A third is a boundary error in the "xpm_extract_color()" function, again when decoding XPM images. This can also cause a buffer overlow. And lastly, an input validation error in ICO image decoding can cause an integer overflow, causing a crash.

Secunia says in its advisory that there is no official updated version of GdkPixBuf. However, so far, Red Hat, Debian, Fedora and MandrakeSoft have all put out updates and patches.

Earlier this week Microsoft reported a security flaw in the way many of its applications process JPEG images -- which could allow an attacker to gain control over a computer running the software.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
