Insight
It was discovered that incorrect memory handling in the png_set_text2() function of the PNG library could lead to the execution of arbitrary code. For the stable distribution (squeeze), this problem has been fixed in version libpng_1.2.44-1+squeeze4. For the unstable distribution (sid), this problem will be fixed soon. We recommend that you upgrade your incorrect memory handling packages.
