Synopsis ========
An integer overflow in TigerVNC might allow remote attackers to execute arbitrary code.
Background ==========
TigerVNC is a high-performance VNC server/client.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/tigervnc < 1.4.2 >= 1.4.2
Description ===========
TigerVNC is impacted by the same vulnerability as found in CVE-2014-6051. An integer overflow, leading to a heap-based buffer overflow, was found in the way screen sizes were handled.
Impact ======
A remote attacker, utilizing a malicious VNC server, could execute arbitrary code with the privileges of the user running the client, or cause a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All TigerVNC users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/tigervnc-1.4.2"
