- Developers of the PNG library have fixed a buffer overflow in the
- progressive reader when the PNG datastream contains more IDAT data
- than indicated by the IHDR chunk. Such deliberately malformed
- datastreams would crash applications which could potentially allow an
- attacker to execute malicious code. Programs such as Galeon,
- Konqueror and various others make use of these libraries.
- In addition to that, the packages below fix another
- potential buffer overflow. The PNG libraries implement a safety
- margin which is also included in a newer upstream release. Thanks to
- Glenn Randers-Pehrson for informing us.
- To find out which packages depend on this library, you may want to
- execute the following commands:
-
- apt-cache showpkg libpng2
- apt-cache showpkg libpng3
-
-
- This problem has been fixed in version 1.0.12-3.woody.2 of libpng and
- version 1.2.1-1.1.woody.2 of libpng3 for the current stable
- distribution (woody) and in version 1.0.12-4 of libpng and version
- 1.2.1-2 of libpng3 for the unstable distribution (sid).
- The potato release of Debian does not seem to be vulnerable.
- We recommend that you upgrade your libpng packages immediately and
- restart programs and daemons that link to these libraries and read
- external data, such as web browsers.
