Updated spice-gtk packages fix security vulnerability

Publication date: 22 Feb 2019
Type: security
Affected Mageia releases : 6
CVE: CVE-2017-12194 , CVE-2018-10873 , CVE-2018-10893


A flaw was found in the way spice-client processed certain messages sent
from the server. An attacker, having control of malicious spice-server,
could use this flaw to crash the client or execute arbitrary code with
permissions of the user running the client. spice-gtk versions through
0.34 are believed to be vulnerable. (CVE-2017-12194)

A vulnerability was discovered in SPICE before version 0.14.1 where the
generated code used for demarshalling messages lacked sufficient bounds
checks. A malicious client or server, after authentication, could send
specially crafted messages to its peer which would result in a crash or,
potentially, other impacts. (CVE-2018-10873)

Multiple integer overflow and buffer overflow issues were discovered in
spice-client's handling of LZ compressed frames. A malicious server could
cause the client to crash or, potentially, execute arbitrary code.
