CVE-2018-5097 – Mozilla: Use-after-free when source document is manipulated during XSLT (MFSA 2018-03)
https://notcve.org/view.php?id=CVE-2018-5097
A use-after-free vulnerability can occur during XSL transformations when the source document for the transformation is manipulated by script content during the transformation. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada durante las transformaciones XSL cuando el documento de origen para la transformación se manipula con scripts durante la transformación. Esto resulta en un cierre inesperado explotable. • http://www.securityfocus.com/bid/102783 http://www.securitytracker.com/id/1040270 https://access.redhat.com/errata/RHSA-2018:0122 https://access.redhat.com/errata/RHSA-2018:0262 https://bugzilla.mozilla.org/show_bug.cgi?id=1387427 https://lists.debian.org/debian-lts-announce/2018/01/msg00030.html https://lists.debian.org/debian-lts-announce/2018/01/msg00036.html https://usn.ubuntu.com/3544-1 https://www.debian.org/security/2018/dsa-4096 https://www.debian.org/securi • CWE-416: Use After Free •
CVE-2017-18075 – kernel: Mishandled freeing of instances in pcrypt.c can allow a local user to cause a denial of service
https://notcve.org/view.php?id=CVE-2017-18075
crypto/pcrypt.c in the Linux kernel before 4.14.13 mishandles freeing instances, allowing a local user able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls. crypto/pcrypt.c en el kernel de Linux en versiones anteriores a la 4.14.13 gestiona de manera incorrecta la liberación de instancias, lo que permite que un usuario local acceda a la interfaz AEAD basada en AF_ALG (CONFIG_CRYPTO_USER_API_AEAD) y pcrypt (CONFIG_CRYPTO_PCRYPT) para provocar una denegación de servicio (kfree de un puntero incorrecto) o, posiblemente, causar otro tipo de impacto sin especificar mediante la ejecución de una secuencia manipulada de llamadas del sistema. crypto/pcrypt.c in the Linux kernel, before 4.14.13, mishandles freeing instances, allowing a local user able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d76c68109f37cb85b243a1cf0f40313afd2bae68 http://www.securityfocus.com/bid/102813 https://access.redhat.com/errata/RHSA-2018:2948 https://github.com/torvalds/linux/commit/d76c68109f37cb85b243a1cf0f40313afd2bae68 https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.13 https://access.redhat.com/security/cve/CVE-2017-18075 https://bugzilla.redhat.com • CWE-628: Function Call with Incorrectly Specified Arguments CWE-763: Release of Invalid Pointer or Reference •
CVE-2018-5683 – Qemu: Out-of-bounds read in vga_draw_text routine
https://notcve.org/view.php?id=CVE-2018-5683
The vga_draw_text function in Qemu allows local OS guest privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging improper memory address validation. La función vga_draw_text en Qemu permite que usuarios del sistema operativo invitados con privilegios provoquen una denegación de servicio (acceso de lectura fuera de límites y cierre inesperado del proceso Qemu) aprovechando la validación indebida de direcciones de memoria. An out-of-bounds read access issue was found in the VGA emulator of QEMU. It could occur in vga_draw_text routine, while updating display area for a vnc client. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS. • http://www.openwall.com/lists/oss-security/2018/01/15/2 http://www.securityfocus.com/bid/102518 https://access.redhat.com/errata/RHSA-2018:0816 https://access.redhat.com/errata/RHSA-2018:1104 https://access.redhat.com/errata/RHSA-2018:2162 https://lists.debian.org/debian-lts-announce/2018/09/msg00007.html https://lists.gnu.org/archive/html/qemu-devel/2018-01/msg02597.html https://usn.ubuntu.com/3575-1 https://www.debian.org/security/2018/dsa-4213 https:/ • CWE-125: Out-of-bounds Read •
CVE-2018-5950 – mailman: Cross-site scripting (XSS) vulnerability in web UI
https://notcve.org/view.php?id=CVE-2018-5950
Cross-site scripting (XSS) vulnerability in the web UI in Mailman before 2.1.26 allows remote attackers to inject arbitrary web script or HTML via a user-options URL. Vulnerabilidad de Cross-Site Scripting (XSS) en la interfaz de usuario web en Mailman en versiones anteriores a la 2.1.26 permite que atacantes remotos inyecten scripts web o HTML arbitrarios mediante una URL user-options. A cross-site scripting (XSS) flaw was found in mailman. An attacker, able to trick the user into visiting a specific URL, can execute arbitrary web scripts on the user's side and force the victim to perform unintended actions. Mailman versions 1.x up through 2.1.23 suffer from a cross site scripting vulnerability. • http://packetstormsecurity.com/files/159761/Mailman-2.1.23-Cross-Site-Scripting.html http://www.securityfocus.com/bid/104594 https://access.redhat.com/errata/RHSA-2018:0504 https://access.redhat.com/errata/RHSA-2018:0505 https://bugs.launchpad.net/mailman/+bug/1747209 https://lists.debian.org/debian-lts-announce/2018/02/msg00007.html https://usn.ubuntu.com/3563-1 https://www.debian.org/security/2018/dsa-4108 https://www.mail-archive.com/mailman-users%40python.org/msg70375. • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2017-15105
https://notcve.org/view.php?id=CVE-2017-15105
A flaw was found in the way unbound before 1.6.8 validated wildcard-synthesized NSEC records. An improperly validated wildcard NSEC record could be used to prove the non-existence (NXDOMAIN answer) of an existing wildcard record, or trick unbound into accepting a NODATA proof. Se ha encontrado un error en la forma en la que unbound, en versiones anteriores a la 1.6.8, validaba los registros NSEC sintetizados con caracteres comodín. Un registro con caracteres comodín NSEC validado incorrectamente podría emplearse para probar la falta (respuesta NXDOMAIN) de un registro de caracteres comodín, o engañar a unbound para que acepte una prueba NODATA. • http://www.securityfocus.com/bid/102817 https://lists.debian.org/debian-lts-announce/2018/01/msg00039.html https://lists.debian.org/debian-lts-announce/2019/02/msg00022.html https://unbound.net/downloads/CVE-2017-15105.txt https://usn.ubuntu.com/3673-1 • CWE-20: Improper Input Validation CWE-358: Improperly Implemented Security Check for Standard •
