Several vulnerabilities were discovered in imlib2, an image manipulation library.


Kevin Ryde discovered that attempting to draw a 2x1 radi ellipse
results in a floating point exception.


It was discovered that an integer overflow could lead to invalid
memory reads and unreasonably large memory allocations.


Yuriy M. Kaminskiy discovered that drawing using coordinates from
an untrusted source could lead to an out-of-bound memory read, which
in turn could result in an application crash.


Jakub Wilk discovered that a malformed image could lead to an
out-of-bound read in the GIF loader, which may result in an
application crash or information leak.


Yuriy M. Kaminskiy discovered an integer overflow that could lead to
an insufficient heap allocation and out-of-bound memory write.

For the oldstable distribution (wheezy), these problems have been fixed in version 1.4.5-1+deb7u2.
