389-ds-base before versions 1.4.0.9, 1.3.8.1, 1.3.6.15 did not properly handle long search filters with characters needing escapes, possibly leading to buffer overflows. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service. 389-ds-base en versiones anteriores a la 1.4.0.9, 1.3.8.1 y 1.3.6.15 no gestionó correctamente los filtros de búsqueda largos con caracteres que necesitan escapado. Esto podría conducir a desbordamientos de búfer. Un atacante remoto no autenticado podría emplear este error para hacer que ns-slapd se cierre inesperadamente mediante una petición LDAP especialmente manipulada que resulta en una denegación de servicio (DoS).

CVSS: 8.0EPSS: 0%CPEs: 24EXPL: 0CVE-2018-1087 – Kernel: KVM: error in exception handling leads to wrong debug stack value
https://notcve.org/view.php?id=CVE-2018-1087
kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest. kernel KVM en versiones anteriores al kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 y kernel 4.17-rc3 es vulnerable a un error en la forma en la que el hipervisor KVM del kernel de Linux gestiona las excepciones lanzadas tras una operación de cambio de pila mediante instrucciones Mov SS o Pop SS. Durante la operación de cambio de pila, el procesador no lanzó interrupciones y excepciones, sino que las lanza una vez se ha ejecutado la primera instrucción tras el cambio de pila. Un usuario invitado sin privilegios de KVM podría usar este error para provocar el cierre inesperado del guest o escalar sus privilegios en el guest. • http://www.openwall.com/lists/oss-security/2018/05/08/5 http://www.securityfocus.com/bid/104127 http://www.securitytracker.com/id/1040862 https://access.redhat.com/errata/RHSA-2018:1318 https://access.redhat.com/errata/RHSA-2018:1345 https://access.redhat.com/errata/RHSA-2018:1347 https://access.redhat.com/errata/RHSA-2018:1348 https://access.redhat.com/errata/RHSA-2018:1355 https://access.redhat.com/errata/RHSA-2018:1524 https://access.redhat.com/security/vulnerabili • CWE-250: Execution with Unnecessary Privileges •

There is a stack-based buffer over-read in calling GLib in the function gxps_images_guess_content_type of gxps-images.c in libgxps through 0.3.0 because it does not reject negative return values from a g_input_stream_read call. A crafted input will lead to a remote denial of service attack.
