A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIChangeProperty request has a length-validation issues, resulting in out-of-bounds memory reads and potential information disclosure. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. Se encontró una vulnerabilidad en X.Org. Esta falla de seguridad se produce porque el controlador de la solicitud XIChangeProperty tiene problemas de validación de longitud, lo que genera lecturas de memoria fuera de los límites y una posible divulgación de información. • http://www.openwall.com/lists/oss-security/2023/12/13/1 https://access.redhat.com/security/cve/CVE-2022-46344 https://bugzilla.redhat.com/show_bug.cgi?id=2151760 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5NELB7YDWRABYYBG4UPTHRBDTKJRV5M2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DXDF2O5PPLE3SVAJJYUOSAD5QZ4TWQ2G https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z67QC4C3I2FI2WRFIUPEHKC36J36 • CWE-125: Out-of-bounds Read •

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service.

CVSS: 7.0EPSS: 0%CPEs: 6EXPL: 1CVE-2021-3864
https://notcve.org/view.php?id=CVE-2021-3864
A flaw was found in the way the dumpable flag setting was handled when certain SUID binaries executed its descendants. The prerequisite is a SUID binary that sets real UID equal to effective UID, and real GID equal to effective GID. The descendant will then have a dumpable value set to 1. As a result, if the descendant process crashes and core_pattern is set to a relative value, its core dump is stored in the current directory with uid:gid permissions. An unprivileged local user with eligible root SUID binary could use this flaw to place core dumps into root-owned directories, potentially resulting in escalation of privileges. • https://access.redhat.com/security/cve/CVE-2021-3864 https://bugzilla.redhat.com/show_bug.cgi?id=2015046 https://lore.kernel.org/all/20211221021744.864115-1-longman%40redhat.com https://lore.kernel.org/all/20211226150310.GA992%401wt.eu https://lore.kernel.org/lkml/20211228170910.623156-1-wander%40redhat.com https://security-tracker.debian.org/tracker/CVE-2021-3864 https://www.openwall.com/lists/oss-security/2021/10/20/2 • CWE-284: Improper Access Control •
