Summary
Red Hat Security Advisory: : Updated libpng packages fix crash

Notes

Topic
Updated libpng packages that fix a out of bounds memory access are now available.
Details
The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. Steve Grubb discovered a out of bounds memory access flaw in libpng. An attacker could carefully craft a PNG file in such a way that it would cause an application linked to libpng to crash when opened by a victim. This issue may not be used to execute arbitrary code. Users are advised to upgrade to these updated packages that contain a backported security fix not vulnerable to this issue.

Only those\nRPMs which are currently installed will be updated.  Those RPMs which are\nnot installed but included in the list will not be updated.  Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network.  Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.\n\nIf up2date fails to connect to Red Hat Network due to SSL\nCertificate Errors, you need to install a version of the\nup2date client with an updated certificate.  The latest version of\nup2date is available from the Red Hat FTP site and may also be\ndownloaded directly from the RHN website:\n\nhttps://rhn.redhat.com/help/latest-up2date.pxt",
