LibVNCServer was updated to version 0.9.10 to fix several security and non-security issues.
The following issues were fixed :
Remove xorg-x11-devel from buildRequires, X libraries are not directly used/linked
libvncserver-0.9.10-ossl.patch: Update, do not RAND_load_file(‘/dev/urandom’, 1024) if the the PRNG is already seeded. (It always is on linux)
Update to version 0.9.10
Moved the whole project from sourceforge to https://libvnc.github.io/.
Cleaned out the autotools build system which now uses autoreconf.
Updated noVNC HTML5 client to latest version.
Split out x11vnc sources into separate repository at https://github.com/LibVNC/x11vnc
Split out vncterm sources into separate repository at https://github.com/LibVNC/vncterm
Split out VisualNaCro sources into separate repository at https://github.com/LibVNC/VisualNaCro
Merged Debian patches.
Fixed some security-related buffer overflow cases.
Added compatibility headers to make LibVNCServer/LibVNCClient build on native Windows 8.
Update LZO to version 2.07, fixing CVE-2014-4607.
Merged patches from KDE/krfb.
Can now do IPv6 without IPv4.
Fixed a use-after-free issue in scale.c.
Update Url and download source to new project home
Remove LibVNCServer-0.9.9-no_x11vnc.patch; upstream splited it out of main tarball
Rebase libvncserver-ossl.patch to upstream changes > libvncserver-0.9.10-ossl.patch
Remove linuxvnc subpackage; like x11vnc, it has been splited out but is depreciated and unmaintained.
