Two vulnerabilities have been reported in libpng, which potentially can be exploited by malicious people to compromise a user's system.
A boundary error in the "png_handle_tRNS()" function and an integer overflow in the "png_read_png()" function can be exploited to cause buffer overflows by tricking a user into viewing a specially crafted PNG image with an application linked to the vulnerable library.
Successful exploitation may allow execution of arbitrary code.
