SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200906-01 (libpng: Information disclosure)
Jeff Phillips discovered that libpng does not properly parse 1-bit interlaced images with width values that are not divisible by 8, which causes libpng to include uninitialized bits in certain rows of a PNG file.
A remote attacker might entice a user to open a specially crafted PNG file, possibly resulting in the disclosure of sensitive memory portions.
There is no known workaround at this time.
SolutionAll libpng users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libpng-1.2.37'
