The QSvg module in Qt, as used in the Mumble client 1.2.x before 1.2.6, allows remote attackers to cause a denial of service (hang and resource consumption) via a local file reference in an (1) image tag or (2) XML stylesheet in an SVG file.

mumble was updated to fix two security issues.

  - The Mumble client did not properly HTML-escape some     external strings before using them in a rich-text (HTML)     context (CVE-2014-3756).

  - SVG images with local file references could trigger     client DoS (CVE-2014-3755).

The remote host is affected by the vulnerability described in GLSA-201406-06 (Mumble: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mumble:
      A crafted length prefix value can trigger a heap-based buffer         overflow or NULL pointer dereference in the         opus_packet_get_samples_per_frame function (CVE-2014-0044)       A crafted packet can trigger an error in the opus_decode_float         function, leading to a heap-based buffer overflow (CVE-2014-0045)       A crafted SVG referencing local files can lead to resource exhaustion         or hangs (CVE-2014-3755)       Mumble does not properly escape HTML in some external strings before         displaying them (CVE-2014-3756)   Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

New upstream release 1.2.6.

This update fixes :

  - CVE-2014-3755

    - CVE-2014-3756
