CVE-2018-1000156 – patch: Malicious patch files cause ed to execute arbitrary commands
https://notcve.org/view.php?id=CVE-2018-1000156
GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time. La versión 2.7.6 de GNU Patch contiene una vulnerabilidad de validación de entradas al procesar archivos patch; específicamente la invocación EDITOR_PROGRAM (usando ed) puede resultar en la ejecución de código. el ataque parece ser explotable mediante un archivo patch procesado mediante la utilidad patch. Esto es similar al CVE-2015-1418 de FreeBSD: aunque comparten un ancestro común, las bases de código han divergido con el tiempo. • http://packetstormsecurity.com/files/154124/GNU-patch-Command-Injection-Directory-Traversal.html http://rachelbythebay.com/w/2018/04/05/bangpatch https://access.redhat.com/errata/RHSA-2018:1199 https://access.redhat.com/errata/RHSA-2018:1200 https://access.redhat.com/errata/RHSA-2018:2091 https://access.redhat.com/errata/RHSA-2018:2092 https://access.redhat.com/errata/RHSA-2018:2093 https://access.redhat.com/errata/RHSA-2018:2094 https://access.redhat.com/errata/RHSA-2018:2095 ht • CWE-20: Improper Input Validation CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVE-2018-1000140 – librelp: Stack-based buffer overflow in relpTcpChkPeerName function in src/tcp.c
https://notcve.org/view.php?id=CVE-2018-1000140
rsyslog librelp version 1.2.14 and earlier contains a Buffer Overflow vulnerability in the checking of x509 certificates from a peer that can result in Remote code execution. This attack appear to be exploitable a remote attacker that can connect to rsyslog and trigger a stack buffer overflow by sending a specially crafted x509 certificate. rsyslog librelp en versiones 1.2.14 y anteriores contiene una vulnerabilidad de desbordamiento de búfer en la verificación de certificados x509 desde un peer que puede resultar en la ejecución remota de código. Parece que este ataque puede ser explotable debido a que un atacante remoto puede conectarse a rsyslog y desencadena un desbordamiento de búfer basado en pila mediante el envío de un certificado x509 especialmente manipulado. A stack-based buffer overflow was found in the way librelp parses X.509 certificates. By connecting or accepting connections from a remote peer, an attacker may use a specially crafted X.509 certificate to exploit this flaw and potentially execute arbitrary code. • https://github.com/s0/rsyslog-librelp-CVE-2018-1000140 https://github.com/s0/rsyslog-librelp-CVE-2018-1000140-fixed http://packetstormsecurity.com/files/172829/librelp-Remote-Code-Execution.html https://access.redhat.com/errata/RHSA-2018:1223 https://access.redhat.com/errata/RHSA-2018:1225 https://access.redhat.com/errata/RHSA-2018:1701 https://access.redhat.com/errata/RHSA-2018:1702 https://access.redhat.com/errata/RHSA-2018:1703 https://access.redhat.com/errata/RHSA-2018:1704 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2016-9600 – jasper: JP2 encoder NULL pointer dereference due to uninitialized cmprof_
https://notcve.org/view.php?id=CVE-2016-9600
JasPer before version 2.0.10 is vulnerable to a null pointer dereference was found in the decoded creation of JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash. JasPer, en versiones anteriores a la 2.0.10, es vulnerable a una desreferencia de puntero NULL, tal y como se descubrió en la creación descifrada de archivos de imagen JPEG 2000. Un archivo especialmente manipulado podría provocar el cierre inesperado de una aplicación que esté utilizando JasPer. • https://access.redhat.com/errata/RHSA-2017:1208 https://bugzilla.redhat.com/show_bug.cgi?id=1410026 https://usn.ubuntu.com/3693-1 https://access.redhat.com/security/cve/CVE-2016-9600 • CWE-476: NULL Pointer Dereference •
CVE-2018-5117 – Mozilla: URL spoofing with right-to-left text aligned left-to-right (MFSA 2018-03)
https://notcve.org/view.php?id=CVE-2018-5117
If right-to-left text is used in the addressbar with left-to-right alignment, it is possible in some circumstances to scroll this text to spoof the displayed URL. This issue could result in the wrong URL being displayed as a location, which can mislead users to believe they are on a different site than the one loaded. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58. Si se utiliza texto de derecha a izquierda en la barra de direcciones con alineación de izquierda a derecha, en algunas circunstancias es posible desplazar este texto para falsificar la URL mostrada. Este problema puede provocar que se muestre una URL incorrecta como ubicación, lo que puede inducir a los usuarios a error al creer que se encuentran en un sitio diferente al que se ha cargado. • 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=1395508 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-451: User Interface (UI) Misrepresentation of Critical Information •
