Fedora 7 : libpng10-1.0.29-1.fc7 (2007-2521)

Medium Nessus Plugin ID 27775


The remote Fedora host is missing a security update.


Certain chunk handlers in libpng10 before 1.0.29 allow remote attackers to cause a denial of service (crash) via crafted (1) pCAL (png_handle_pCAL), (2) sCAL (png_handle_sCAL), (3) tEXt (png_push_read_tEXt), (4) iTXt (png_handle_iTXt), and (5) ztXT (png_handle_ztXt) chunking in PNG images, which trigger out-of-bounds read operations.

This update to 1.0.29 addresses these issues.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libpng10, libpng10-debuginfo and / or libpng10-devel packages.
