Vulnerability Assessment Details
imlib2: Multiple vulnerabilities
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200612-20
(imlib2: Multiple vulnerabilities)
M. Joonas Pihlaja discovered several buffer overflows in loader_argb.c,
loader_png.c, loader_lbm.c, loader_jpeg.c, loader_tiff.c, loader_tga.c,
loader_pnm.c and an out-of-bounds memory read access in loader_tga.c.
A possible hacker can entice a user to process a specially crafted JPG, ARGB,
PNG, LBM, PNM, TIFF, or TGA image with an "imlib2*" binary or another
application using the imlib2 libraries. Successful exploitation of the
buffer overflows causes the execution of arbitrary code with the
permissions of the user running the application.
There is no known workaround at this time.
All imlib2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.3.0"
Network Security Threat Level: Medium
