CVE-2018-18505 [CRITICAL] CVE-2018-18505: An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authenti An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later chann

CVE-2018-18506 [MEDIUM] CVE-2018-18506: When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file o When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attack

CVE-2019-3813 [HIGH] CWE-193 CVE-2019-3813: Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one e Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt. This may lead to a denial of service, or, in the worst case, code-execution by unauthenticated attackers.

CVE-2019-3815 [LOW] CVE-2019-3815: A memory leak was discovered in the backport of fixes for CVE-2018-16864 in Red Hat Enterprise Linux A memory leak was discovered in the backport of fixes for CVE-2018-16864 in Red Hat Enterprise Linux.
