CVE-2018-18495 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
WebExtension content scripts can be loaded into about: pages in some circumstances, in violation of the permissions granted to extensions. This could allow an extension to interfere with the loading and usage of these pages and use capabilities that were intended to be restricted from extensions. This vulnerability affects Firefox < 64.
CVE-2018-18494 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
A same-origin policy violation allowing the theft of cross-origin URL entries when using the Javascript location property to cause a redirection to another site using performance.getEntries(). This is a same-origin policy violation and could allow for data theft. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.
CVE-2018-18493 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.
CVE-2018-18492 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur after deleting a selection element due to a weak reference to the select element in the options collection. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.
CVE-2018-18445 3 Canonical, Linux, Redhat 8 Ubuntu Linux, Linux Kernel, Enterprise Linux Desktop and 5 more 2024-11-21 7.2 HIGH 7.8 HIGH
In the Linux kernel 4.14.x, 4.15.x, 4.16.x, 4.17.x, and 4.18.x before 4.18.13, faulty computation of numeric bounds in the BPF verifier permits out-of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandles 32-bit right shifts.
CVE-2018-18409 3 Canonical, Digitalcorpora, Fedoraproject 3 Ubuntu Linux, Tcpflow, Fedora 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A stack-based buffer over-read exists in setbit() at iptree.h of TCPFLOW 1.5.0, due to received incorrect values causing incorrect computation, leading to denial of service during an address_histogram call or a get_histogram call.
CVE-2018-18397 3 Canonical, Linux, Redhat 10 Ubuntu Linux, Linux Kernel, Enterprise Linux Desktop and 7 more 2024-11-21 2.1 LOW 5.5 MEDIUM
The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c.
CVE-2018-18386 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-11-21 2.1 LOW 3.3 LOW
drivers/tty/n_tty.c in the Linux kernel before 4.14.11 allows local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ.
CVE-2018-18356 5 Canonical, Debian, Google and 2 more 10 Ubuntu Linux, Debian Linux, Chrome and 7 more 2024-11-21 6.8 MEDIUM 8.8 HIGH
An integer overflow in path handling lead to a use after free in Skia in Google Chrome prior to 71.0.3578.80 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
CVE-2018-18314 5 Canonical, Debian, Netapp and 2 more 8 Ubuntu Linux, Debian Linux, E-series Santricity Os Controller and 5 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Perl before 5.26.3 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
CVE-2018-18313 6 Apple, Canonical, Debian and 3 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2024-11-21 6.4 MEDIUM 9.1 CRITICAL
Perl before 5.26.3 has a buffer over-read via a crafted regular expression that triggers disclosure of sensitive information from process memory.
CVE-2018-18312 5 Canonical, Debian, Netapp and 2 more 8 Ubuntu Linux, Debian Linux, E-series Santricity Os Controller and 5 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Perl before 5.26.3 and 5.28.0 before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
CVE-2018-18311 8 Apple, Canonical, Debian and 5 more 18 Mac Os X, Ubuntu Linux, Debian Linux and 15 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Perl before 5.26.3 and 5.28.x before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
CVE-2018-18310 5 Canonical, Debian, Elfutils Project and 2 more 7 Ubuntu Linux, Debian Linux, Elfutils and 4 more 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
An invalid memory address dereference was discovered in dwfl_segment_report_module.c in libdwfl in elfutils through v0.174. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by consider_notes.
CVE-2018-18284 5 Artifex, Canonical, Debian and 2 more 11 Ghostscript, Gpl Ghostscript, Ubuntu Linux and 8 more 2024-11-21 6.8 MEDIUM 8.6 HIGH
Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving the 1Policy operator.
CVE-2018-18281 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 4.6 MEDIUM 7.8 HIGH
Since Linux kernel version 3.2, the mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. This is fixed in the following kernel versions: 4.9.135, 4.14.78, 4.18.16, 4.19.
CVE-2018-18074 4 Canonical, Opensuse, Python and 1 more 6 Ubuntu Linux, Leap, Requests and 3 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network.
CVE-2018-18073 4 Artifex, Canonical, Debian and 1 more 9 Ghostscript, Ubuntu Linux, Debian Linux and 6 more 2024-11-21 4.3 MEDIUM 6.3 MEDIUM
Artifex Ghostscript allows attackers to bypass a sandbox protection mechanism by leveraging exposure of system operators in the saved execution stack in an error object.
CVE-2018-18065 5 Canonical, Debian, Net-snmp and 2 more 10 Ubuntu Linux, Debian Linux, Net-snmp and 7 more 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
_set_key in agent/helpers/table_container.c in Net-SNMP before 5.8 has a NULL Pointer Exception bug that can be used by an authenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in Denial of Service.
CVE-2018-18021 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 3.6 LOW 7.1 HIGH
arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes.
