PNG library vulnerabilities
Releases
Details
Several integer overflow vulnerabilities were discovered in the PNG library.
These vulnerabilities could be exploited by an attacker by providing a
specially crafted PNG image which, when processed by the PNG library, could
result in the execution of program code provided by the attacker.
The PNG library is used by a variety of software packages for different
purposes, so the exact nature of the exposure will vary depending on the
software involved.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 4.10
-
libpng10-0
-
-
libpng12-dev
-
-
libpng12-0
-
-
libpng10-dev
-
In general, a standard system update will make all the necessary changes.
