LibVNCServer was updated to fix two security issues.
These security issues were fixed:
- CVE-2018-7225: Missing input sanitization inside rfbserver.c
rfbProcessClientNormalMessage() (bsc#1081493).
- CVE-2016-9942: Heap-based buffer overflow in ultra.c allowed remote
servers to cause a denial of service (application crash) or possibly
execute arbitrary code via a crafted FramebufferUpdate message with the
Ultra type tile, such that the LZO payload decompressed length exceeds
what is specified by the tile dimensions (bsc#1017712).
- CVE-2016-9941: Heap-based buffer overflow in rfbproto.c allowed remote
servers to cause a denial of service (application crash) or possibly
execute arbitrary code via a crafted FramebufferUpdate message
containing a subrectangle outside of the client drawing area
(bsc#1017711).
