OptiPNG: User-assisted execution of arbitrary code

OptiPNG: User-assisted execution of arbitrary code A vulnerability in OptiPNG might result in user-assisted execution of arbitrary code. optipng 2008-12-02 2008-12-02 246522 remote 0.6.2 0.6.2

OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information.

A buffer overflow in the BMP reader in OptiPNG has been reported.

A remote attacker could entice a user to process a specially crafted BMP image, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.

There is no known workaround at this time.

All OptiPNG users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/optipng-0.6.2"
