gdk-pixbuf vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
Summary:
GDK-PixBuf could be made to crash or run programs as your login if it
opened a specially crafted file.
Software Description:
- gdk-pixbuf: GDK Pixbuf library
Details:
Gustavo Grieco discovered that the GDK-PixBuf library did not properly
handle scaling tga image files, leading to a heap overflow. If a
user or automated system were tricked into opening a tga image file,
a remote attacker could use this flaw to cause GDK-PixBuf to crash,
resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2015-7673)
Gustavo Grieco discovered that the GDK-PixBuf library contained
an integer overflow when handling certain GIF images. If a user
or automated system were tricked into opening a GIF image file,
a remote attacker could use this flaw to cause GDK-PixBuf to crash,
resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2015-7674)
