CVE-2018-12396 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
A vulnerability where a WebExtension can run content scripts in disallowed contexts following navigation or other events. This allows for potential privilege escalation by the WebExtension on sites where content scripts should not be run. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63.
CVE-2018-12891 2 Debian, Xen 2 Debian Linux, Xen 2019-10-02 4.9 MEDIUM 6.5 MEDIUM
An issue was discovered in Xen through 4.10.x. Certain PV MMU operations may take a long time to process. For that reason Xen explicitly checks for the need to preempt the current vCPU at certain points. A few rarely taken code paths did bypass such checks. By suitably enforcing the conditions through its own page table contents, a malicious guest may cause such bypasses to be used for an unbounded number of iterations. A malicious or buggy PV guest may cause a Denial of Service (DoS) affecting the entire host. Specifically, it may prevent use of a physical CPU for an indeterminate period of time. All Xen versions from 3.4 onwards are vulnerable. Xen versions 3.3 and earlier are vulnerable to an even wider class of attacks, due to them lacking preemption checks altogether in the affected code paths. Only x86 systems are affected. ARM systems are not affected. Only multi-vCPU x86 PV guests can leverage the vulnerability. x86 HVM or PVH guests as well as x86 single-vCPU PV ones cannot leverage the vulnerability.
CVE-2018-12893 2 Debian, Xen 2 Debian Linux, Xen 2019-10-02 2.1 LOW 6.5 MEDIUM
An issue was discovered in Xen through 4.10.x. One of the fixes in XSA-260 added some safety checks to help prevent Xen livelocking with debug exceptions. Unfortunately, due to an oversight, at least one of these safety checks can be triggered by a guest. A malicious PV guest can crash Xen, leading to a Denial of Service. All Xen systems which have applied the XSA-260 fix are vulnerable. Only x86 systems are vulnerable. ARM systems are not vulnerable. Only x86 PV guests can exploit the vulnerability. x86 HVM and PVH guests cannot exploit the vulnerability. An attacker needs to be able to control hardware debugging facilities to exploit the vulnerability, but such permissions are typically available to unprivileged users.
CVE-2018-1304 5 Apache, Canonical, Debian and 2 more 11 Tomcat, Ubuntu Linux, Debian Linux and 8 more 2019-10-02 4.3 MEDIUM 5.9 MEDIUM
The URL pattern of "" (the empty string) which exactly maps to the context root was not correctly handled in Apache Tomcat 9.0.0.M1 to 9.0.4, 8.5.0 to 8.5.27, 8.0.0.RC1 to 8.0.49 and 7.0.0 to 7.0.84 when used as part of a security constraint definition. This caused the constraint to be ignored. It was, therefore, possible for unauthorised users to gain access to web application resources that should have been protected. Only security constraints with a URL pattern of the empty string were affected.
CVE-2018-1305 4 Apache, Canonical, Debian and 1 more 6 Tomcat, Ubuntu Linux, Debian Linux and 3 more 2019-10-02 4.0 MEDIUM 6.5 MEDIUM
Security constraints defined by annotations of Servlets in Apache Tomcat 9.0.0.M1 to 9.0.4, 8.5.0 to 8.5.27, 8.0.0.RC1 to 8.0.49 and 7.0.0 to 7.0.84 were only applied once a Servlet had been loaded. Because security constraints defined in this way apply to the URL pattern and any URLs below that point, it was possible - depending on the order Servlets were loaded - for some security constraints not to be applied. This could have exposed resources to users who were not authorised to access them.
CVE-2018-13302 2 Debian, Ffmpeg 2 Debian Linux, Ffmpeg 2019-10-02 6.8 MEDIUM 8.8 HIGH
In FFmpeg 4.0.1, improper handling of frame types (other than EAC3_FRAME_TYPE_INDEPENDENT) that have multiple independent substreams in the handle_eac3 function in libavformat/movenc.c may trigger an out-of-array access while converting a crafted AVI file to MPEG4, leading to a denial of service or possibly unspecified other impact.
CVE-2018-14055 2 Debian, Znc 2 Debian Linux, Znc 2019-10-02 4.0 MEDIUM 6.5 MEDIUM
ZNC before 1.7.1-rc1 does not properly validate untrusted lines coming from the network, allowing a non-admin user to escalate his privilege and inject rogue values into znc.conf.
CVE-2018-14347 2 Debian, Gnu 2 Debian Linux, Libextractor 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
GNU Libextractor before 1.7 contains an infinite loop vulnerability in EXTRACTOR_mpeg_extract_method (mpeg_extractor.c).
CVE-2018-14526 3 Canonical, Debian, W1.fi 3 Ubuntu Linux, Debian Linux, Wpa Supplicant 2019-10-02 3.3 LOW 6.5 MEDIUM
An issue was discovered in rsn_supp/wpa.c in wpa_supplicant 2.0 through 2.6. Under certain conditions, the integrity of EAPOL-Key messages is not checked, leading to a decryption oracle. An attacker within range of the Access Point and client can abuse the vulnerability to recover sensitive information.
CVE-2018-14593 2 Debian, Otrs 2 Debian Linux, Open Ticket Request System 2019-10-02 6.5 MEDIUM 8.8 HIGH
An issue was discovered in Open Ticket Request System (OTRS) 6.0.x through 6.0.9, 5.0.x through 5.0.28, and 4.0.x through 4.0.30. An attacker who is logged into OTRS as an agent may escalate their privileges by accessing a specially crafted URL.
CVE-2018-15594 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-10-02 2.1 LOW 5.5 MEDIUM
arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests.
CVE-2018-15572 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-10-02 2.1 LOW 6.5 MEDIUM
The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c in the Linux kernel before 4.18.1 does not always fill RSB upon a context switch, which makes it easier for attackers to conduct userspace-userspace spectreRSB attacks.
CVE-2018-15908 4 Artifex, Canonical, Debian and 1 more 8 Ghostscript, Ubuntu Linux, Debian Linux and 5 more 2019-10-02 6.8 MEDIUM 7.8 HIGH
In Artifex Ghostscript 9.23 before 2018-08-23, attackers are able to supply malicious PostScript files to bypass .tempfile restrictions and write files.
CVE-2018-16645 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
There is an excessive memory allocation issue in the functions ReadBMPImage of coders/bmp.c and ReadDIBImage of coders/dib.c in ImageMagick 7.0.8-11, which allows remote attackers to cause a denial of service via a crafted image file.
CVE-2018-16336 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file, a different vulnerability than CVE-2018-10999.
CVE-2018-16395 4 Canonical, Debian, Redhat and 1 more 5 Ubuntu Linux, Debian Linux, Enterprise Linux and 2 more 2019-10-02 7.5 HIGH 9.8 CRITICAL
An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations.
CVE-2018-16396 4 Canonical, Debian, Redhat and 1 more 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more 2019-10-02 6.8 MEDIUM 8.1 HIGH
An issue was discovered in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. It does not taint strings that result from unpacking tainted strings with some formats.
CVE-2018-16515 2 Debian, Matrix 2 Debian Linux, Synapse 2019-10-02 6.5 MEDIUM 8.8 HIGH
Matrix Synapse before 0.33.3.1 allows remote attackers to spoof events and possibly have unspecified other impacts by leveraging improper transaction and event signature validation.
CVE-2018-16509 4 Artifex, Canonical, Debian and 1 more 8 Ghostscript, Gpl Ghostscript, Ubuntu Linux and 5 more 2019-10-02 9.3 HIGH 7.8 HIGH
An issue was discovered in Artifex Ghostscript before 9.24. Incorrect "restoration of privilege" checking during handling of /invalidaccess exceptions could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction.
CVE-2018-16837 3 Debian, Redhat, Suse 5 Debian Linux, Ansible Engine, Ansible Tower and 2 more 2019-10-02 2.1 LOW 7.8 HIGH
Ansible "User" module leaks any data which is passed on as a parameter to ssh-keygen. This could lean in undesirable situations such as passphrases credentials passed as a parameter for the ssh-keygen executable. Showing those credentials in clear text form for every user which have access just to the process list.
