GLSA-201408-06 : libpng: Multiple vulnerabilities

Medium Nessus Plugin ID 77213


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-201408-06 (libpng: Multiple vulnerabilities)

The png_push_read_chunk function in pngpread.c in the progressive decoder enters an infinite loop, when it encounters a zero-length IDAT chunk. In addition certain integer overflows have been detected and corrected.
The 1.2 branch is not affected by these vulnerabilities.
Impact :

A remote attacker could entice a user to open a specially crafted PNG file using an application linked against libpng, possibly resulting in Denial of Service.
Workaround :

There is no known workaround at this time.


All libpng users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libpng-1.6.10' Users with current installs in the 1.5 branch should also upgrade this using:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libpng-1.5.18:1.5' Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages.
