A flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges. Se ha descubierto un problema en versiones anteriores a la 1.20.3 de xorg-x11-server. Hay una comprobación incorrecta de permisos para las opciones -modulepath y -logfile al iniciar Xorg. • https://www.exploit-db.com/exploits/45938 https://www.exploit-db.com/exploits/45832 https://www.exploit-db.com/exploits/45922 https://www.exploit-db.com/exploits/45908 https://www.exploit-db.com/exploits/45697 https://www.exploit-db.com/exploits/45742 https://www.exploit-db.com/exploits/46142 https://www.exploit-db.com/exploits/47701 https://github.com/jas502n/CVE-2018-14665 https://github.com/bolonobolo/CVE-2018-14665 http://packetstormsecurity.com/files/154942/ • CWE-271: Privilege Dropping / Lowering Errors CWE-863: Incorrect Authorization •
CVSS: 9.8EPSS: 5%CPEs: 6EXPL: 0CVE-2018-14600 – libX11: Out of Bounds write in XListExtensions in ListExt.c
https://notcve.org/view.php?id=CVE-2018-14600
An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading to DoS or remote code execution. Se ha descubierto un problema en libX11 hasta su versión 1.6.5. La función XListExtensions en ListExt.c interpreta una variable como firmada en lugar de no firmada, lo que resulta en una escritura fuera de límites (de hasta 128 bytes), lo que conduce a una denegación de servicio (DoS) o a la ejecución remota de código. An out of bounds write, limited to NULL bytes, was discovered in libX11 in functions XListExtensions() and XGetFontPath(). • http://www.openwall.com/lists/oss-security/2018/08/21/6 http://www.securityfocus.com/bid/105177 http://www.securitytracker.com/id/1041543 https://access.redhat.com/errata/RHSA-2019:2079 https://bugzilla.suse.com/show_bug.cgi?id=1102068 https://cgit.freedesktop.org/xorg/lib/libX11/commit/?id=dbf72805fd9d7b1846fe9a11b46f3994bfc27fea https://lists.debian.org/debian-lts-announce/2018/08/msg00030.html https://lists.x.org/archives/xorg-announce/2018-August/002916.html https://security. • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 1%CPEs: 7EXPL: 0CVE-2018-14598 – libX11: Crash on invalid reply in XListExtensions in ListExt.c
https://notcve.org/view.php?id=CVE-2018-14598
An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed later on, leading to DoS (segmentation fault). Se ha descubierto un problema en XListExtensions en ListExt.c en libX11 hasta la versión 1.6.5. Un servidor malicioso puede enviar una respuesta en la cual la primera cadena se desborda, provocando que una variable se establezca como NULL y se libere posteriormente, lo que conduce a una denegación de servicio (fallo de segmentación). It was discovered that libX11 does not properly validate input coming from the server, causing XListExtensions() and XGetFontPath() functions to produce an invalid list of elements that in turn make XFreeExtensionsList() and XFreeFontPath() access invalid memory. • http://www.openwall.com/lists/oss-security/2018/08/21/6 http://www.securityfocus.com/bid/105177 http://www.securitytracker.com/id/1041543 https://access.redhat.com/errata/RHSA-2019:2079 https://bugzilla.suse.com/show_bug.cgi?id=1102073 https://cgit.freedesktop.org/xorg/lib/libX11/commit/?id=e83722768fd5c467ef61fa159e8c6278770b45c2 https://lists.debian.org/debian-lts-announce/2018/08/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ • CWE-20: Improper Input Validation •
