CVSS: 7.5EPSS: 0%CPEs: 16EXPL: 0CVE-2018-14647 – python: Missing salt initialization in _elementtree.c module
https://notcve.org/view.php?id=CVE-2018-14647
Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by constructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming large amounts CPU and RAM. The vulnerability exists in Python versions 3.7.0, 3.6.0 through 3.6.6, 3.5.0 through 3.5.6, 3.4.0 through 3.4.9, 2.7.0 through 2.7.15. El acelerador de C elementtree en Python no inicializa la sal del hash Expat durante la inicialización. Esto podría facilitar llevar a cabo ataques de denegación de servicio (DoS) contra Expat construyendo un documento XML que provocaría colisiones de hashes en las estructuras internas de datos de Expat, consumiendo grandes cantidades de CPU y RAM. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://www.securityfocus.com/bid/105396 http://www.securitytracker.com/id/1041740 https://access.redhat.com/errata/RHSA-2019:1260 https://access.redhat.com/errata/RHSA-2019:2030 https://access.redhat.com/errata/RHSA-2019:3725 https://bugs.python.org/issue34623 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14647 https://lists.apache.org/thread.html/r1b103833cb5bc8466e24ff0ecc5e75b45a705334ab6a444e64e840a0%40%3Cissues.boo • CWE-335: Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) CWE-665: Improper Initialization CWE-909: Missing Initialization of Resource •
CVSS: 8.3EPSS: 0%CPEs: 20EXPL: 0CVE-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 •

CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-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 •
