SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionLibVNCServer 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).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
