CVE-2018-14357 – mutt: Remote Code Execution via backquote characters
https://notcve.org/view.php?id=CVE-2018-14357
An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. They allow remote IMAP servers to execute arbitrary commands via backquote characters, related to the mailboxes command associated with an automatic subscription. Se ha descubierto un problema en Mutt en versiones anteriores a la 1.10.1 y NeoMutt en versiones anteriores al 2018-07-16. Permiten que los servidores IMAP remotos ejecuten comandos arbitrarios mediante caracteres de acento grave; esto está relacionado con el comando mailboxes asociado con una suscripción automática. • http://www.mutt.org/news.html https://access.redhat.com/errata/RHSA-2018:2526 https://github.com/neomutt/neomutt/commit/e52393740334443ae0206cab2d7caef381646725 https://gitlab.com/muttmua/mutt/commit/185152818541f5cdc059cbff3f3e8b654fc27c1d https://lists.debian.org/debian-lts-announce/2018/08/msg00001.html https://neomutt.org/2018/07/16/release https://security.gentoo.org/glsa/201810-07 https://usn.ubuntu.com/3719-1 https://usn.ubuntu.com/3719-3 https://www.debian.org/security/2018/dsa • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2018-14362 – mutt: POP body caching path traversal vulnerability
https://notcve.org/view.php?id=CVE-2018-14362
An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. pop.c does not forbid characters that may have unsafe interaction with message-cache pathnames, as demonstrated by a '/' character. Se ha descubierto un problema en Mutt en versiones anteriores a la 1.10.1 y NeoMutt en versiones anteriores al 2018-07-16. pop.c no prohíbe los caracteres que podrían interactuar de forma insegura con los nombres de ruta message-cache, tal y como queda demostrado con un carácter "/". • http://www.mutt.org/news.html https://access.redhat.com/errata/RHSA-2018:2526 https://github.com/neomutt/neomutt/commit/9bfab35522301794483f8f9ed60820bdec9be59e https://gitlab.com/muttmua/mutt/commit/6aed28b40a0410ec47d40c8c7296d8d10bae7576 https://lists.debian.org/debian-lts-announce/2018/08/msg00001.html https://neomutt.org/2018/07/16/release https://security.gentoo.org/glsa/201810-07 https://usn.ubuntu.com/3719-3 https://www.debian.org/security/2018/dsa-4277 https://access.redhat.com • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2018-11806 – Qemu Slirp Networking Heap-based Buffer Overflow Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2018-11806
m_cat in slirp/mbuf.c in Qemu has a heap-based buffer overflow via incoming fragmented datagrams. m_cat en slirp/mbuf.c en Qemu tiene un desbordamiento de búfer basado en memoria dinámica (heap) mediante los datagramas entrantes fragmentados. A heap buffer overflow issue was found in the way SLiRP networking back-end in QEMU processes fragmented packets. It could occur while reassembling the fragmented datagrams of an incoming packet. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or potentially leverage it to execute arbitrary code on the host with privileges of the QEMU process. This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of Qemu. • http://www.openwall.com/lists/oss-security/2018/06/07/1 http://www.securityfocus.com/bid/104400 https://access.redhat.com/errata/RHSA-2018:2462 https://access.redhat.com/errata/RHSA-2018:2762 https://access.redhat.com/errata/RHSA-2018:2822 https://access.redhat.com/errata/RHSA-2018:2887 https://access.redhat.com/errata/RHSA-2019:2892 https://bugzilla.redhat.com/show_bug.cgi?id=1586245 https://lists.debian.org/debian-lts-announce/2019/05/msg00010.html https://li • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2018-3639 – AMD / ARM / Intel - Speculative Execution Variant 4 Speculative Store Bypass
https://notcve.org/view.php?id=CVE-2018-3639
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4. Los sistemas con microprocesadores que emplean la ejecución especulativa y que realizan la ejecución especulativa de lecturas de memoria antes de que se conozcan las direcciones de todas las anteriores escrituras de memoria podrían permitir la divulgación no autorizada de información a un atacante con acceso de usuario local mediante un análisis de canal lateral. Esto también se conoce como Speculative Store Bypass (SSB), Variant 4. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). • https://www.exploit-db.com/exploits/44695 https://github.com/mmxsrup/CVE-2018-3639 https://github.com/Shuiliusheng/CVE-2018-3639-specter-v4- https://github.com/malindarathnayake/Intel-CVE-2018-3639-Mitigation_RegistryUpdate http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00007.html http://support.lenovo.com/us/en/solutions/LEN-2213 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVE-2018-2781 – mysql: Server: Optimizer unspecified vulnerability (CPU Apr 2018)

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Optimizer). Supported versions that are affected are 5.5.59 and prior, 5.6.39 and prior and 5.7.21 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.0 Base Score 4.9 (Availability impacts). • http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.securityfocus.com/bid/103825 http://www.securitytracker.com/id/1040698 https://access.redhat.com/errata/RHSA-2018:1254 https://access.redhat.com/errata/RHSA-2018:2439 https://access.redhat.com/errata/RHSA-2018:2729 https://access.redhat.com/errata/RHSA-2018:3655 https://access.redhat.com/errata/RHSA-2019:1258 https://lists.debian.org/debian-lts-announce/2018/04/msg00020.html https://lists. •
