Synopsis
An integer overflow in the PNG handling of Dillo might result in the remote execution of arbitrary code.Background
Dillo is a graphical web browser known for its speed and small footprint.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
www-client/dillo | < 2.1.1 | >= 2.1.1 | All supported architectures |
Description
Tilei Wang reported an integer overflow in the Png_datainfo_callback() function, possibly leading to a heap-based buffer overflow.
Impact
A remote attacker could entice a user to open an HTML document containing a specially crafted, large PNG image, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
Workaround
There is no known workaround at this time.
Resolution
All Dillo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/dillo-2.1.1"
