Ubuntu Security Notice USN-3383-1
August 10, 2017

libsoup2.4 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS


Applications using libsoup could be made to crash or run programs
as your login if it received specially crafted network traffic.

Software Description:
- libsoup2.4: HTTP client/server library for GNOME


Aleksandar Nikolic discovered a stack based buffer overflow when
handling chunked encoding. An attacker could use this to cause a
denial of service or possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 17.04:
  gir1.2-soup-2.4                 2.56.0-2ubuntu0.1
  libsoup-gnome2.4-1              2.56.0-2ubuntu0.1
  libsoup2.4-1                    2.56.0-2ubuntu0.1

Ubuntu 16.04 LTS:
  gir1.2-soup-2.4                 2.52.2-1ubuntu0.2
  libsoup-gnome2.4-1              2.52.2-1ubuntu0.2
  libsoup2.4-1                    2.52.2-1ubuntu0.2

Ubuntu 14.04 LTS:
  gir1.2-soup-2.4                 2.44.2-1ubuntu2.2
  libsoup-gnome2.4-1              2.44.2-1ubuntu2.2
  libsoup2.4-1                    2.44.2-1ubuntu2.2
