Categoría:	Mageia Linux Local Security Checks
Título:	Mageia: Security Advisory (MGASA-2023-0131)
Resumen:	The remote host is missing an update for the 'tigervnc, x11-server' package(s) announced via the MGASA-2023-0131 advisory.
Descripción:	Summary: The remote host is missing an update for the 'tigervnc, x11-server' package(s) announced via the MGASA-2023-0131 advisory. Vulnerability Insight: A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later. (CVE-2023-1393) Affected Software/OS: 'tigervnc, x11-server' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:L/AC:L/Au:S/C:C/I:C/A:C
