CVE-2018-14633 – kernel: stack-based buffer overflow in chap_server_compute_md5() in iscsi target
https://notcve.org/view.php?id=CVE-2018-14633
A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. • http://www.securityfocus.com/bid/105388 https://access.redhat.com/errata/RHSA-2018:3651 https://access.redhat.com/errata/RHSA-2018:3666 https://access.redhat.com/errata/RHSA-2019:1946 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14633 https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git/commit/?h=4.19/scsi-fixes&id=1816494330a83f2a064499d8ed2797045641f92c https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git/commit/?h=4.19/scsi-fixes&id=8c39e2699 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2018-17183 – ghostscript: User-writable error exception table
https://notcve.org/view.php?id=CVE-2018-17183
Artifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code. Artifex Ghostscript en versiones anteriores a la 9.25 permitía una tabla de excepción de error que puede escribir el usuario. Esta tabla podía ser usada por los atacantes remotos capaces de proporcionar PostScript manipulados para poder sobrescribir o reemplazar manipuladores de errores para inyectar código. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=fb713b3818b52d8a6cf62c951eba2e1795ff9624 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.ghostscript.com/show_bug.cgi?id=699708 https://lists.debian.org/debian-lts-announce/2018/09/msg00038.html https://usn.ubuntu.com/3773-1 https://access.redhat.com/security/cve/CVE-2018-17183 https://bugzilla.redhat.com/show_bug.cgi?id=1632471 • CWE-460: Improper Cleanup on Thrown Exception •
CVE-2017-15705 – spamassassin: Certain unclosed tags in crafted emails allow for scan timeouts and result in denial of service
https://notcve.org/view.php?id=CVE-2017-15705
A denial of service vulnerability was identified that exists in Apache SpamAssassin before 3.4.2. The vulnerability arises with certain unclosed tags in emails that cause markup to be handled incorrectly leading to scan timeouts. In Apache SpamAssassin, using HTML::Parser, we setup an object and hook into the begin and end tag event handlers In both cases, the "open" event is immediately followed by a "close" event - even if the tag *does not* close in the HTML being parsed. Because of this, we are missing the "text" event to deal with the object normally. This can cause carefully crafted emails that might take more scan time than expected leading to a Denial of Service. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00002.html http://www.securityfocus.com/bid/105347 https://access.redhat.com/errata/RHSA-2018:2916 https://lists.apache.org/thread.html/7f6a16bc0fd0fd5e67c7fd95bd655069a2ac7d1f88e42d3c853e601c%40%3Cannounce.apache.org%3E https://lists.debian.org/debian-lts-announce/2018/11/msg00016.html https://security.gentoo.org/glsa/201812-07 https://usn.ubuntu.com/3811-1 https://usn.ubuntu.com/3811-2 https://access.redhat.com/security/cve/CVE& • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
CVE-2018-11781 – spamassassin: Local user code injection in the meta rule syntax

Apache SpamAssassin 3.4.2 fixes a local user code injection in the meta rule syntax. Apache SpamAssassin 3.4.2 soluciona una inyección de código de usuario local en la sintaxis de reglas meta. A flaw was found in the way a local user on the SpamAssassin server could inject code in the meta rule syntax. This could cause the arbitrary code execution on the server when these rules are being processed. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00002.html https://access.redhat.com/errata/RHSA-2018:2916 https://lists.apache.org/thread.html/7f6a16bc0fd0fd5e67c7fd95bd655069a2ac7d1f88e42d3c853e601c%40%3Cannounce.apache.org%3E https://lists.debian.org/debian-lts-announce/2018/11/msg00016.html https://security.gentoo.org/glsa/201812-07 https://usn.ubuntu.com/3811-1 https://usn.ubuntu.com/3811-3 https://access.redhat.com/security/cve/CVE-2018-11781 https://bugzilla.redhat.com • CWE-94: Improper Control of Generation of Code ('Code Injection') •
