xzgv: Multiple overflows

xzgv: Multiple overflows xzgv contains multiple overflows that may lead to the execution of arbitrary code. xzgv 2005-01-06 2005-01-06 74069 remote 0.8-r1 0.8

xzgv is a picture viewer for X, with a thumbnail-based file selector.

Multiple overflows have been found in the image processing code of xzgv, including an integer overflow in the PRF parsing code (CAN-2004-0994).

An attacker could entice a user to open or browse a specially-crafted image file, potentially resulting in the execution of arbitrary code with the rights of the user running xzgv.

There is no known workaround at this time.

All xzgv users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/xzgv-0.8-r1"
