Publication date: 22 Feb 2019
URL: https://advisories.mageia.org/MGASA-2019-0099.html
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.
(CVE-2018-10893)
