libpng is a free ANSI C library used to process and manipulate PNG
Mats Palmgren fixed an error in file pngrutil.c in which the trans[]
array might be not allocated because of images with a bad tRNS chunk
CRC value.
<impact type="normal">
A remote attacker could craft an image that when processed or viewed by
an application using libpng causes the application to terminate
There is no known workaround at this time.
Please note that due to separate bugs in libpng 1.2.17, Gentoo does not
provide libpng-1.2.17 but libpng-1.2.18. All libpng users should
upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libpng-1.2.18&quot;</code>
