| 2018-06-11 | CVE-2018-5168 | Sites can bypass security checks on permissions to install lightweight themes by manipulating the "baseURI" property of the theme element. This could allow a malicious site to install a theme without user interaction which could contain offensive or embarrassing images. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8. | Ubuntu_linux, Debian_linux, Firefox, Firefox_esr, Thunderbird, Thunderbird_esr, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_tus, Enterprise_linux_workstation | 5.3 | ||
| 2018-06-11 | CVE-2018-5160 | WebRTC can use a "WrappedI420Buffer" pixel buffer but the owning image object can be freed while it is still in use. This can result in the WebRTC encoder using uninitialized memory, leading to a potentially exploitable crash. This vulnerability affects Firefox < 60. | Ubuntu_linux, Firefox | 7.5 | ||
| 2018-06-11 | CVE-2018-5122 | A potential integer overflow in the "DoCrypt" function of WebCrypto was identified. If a means was found of exploiting it, it could result in an out-of-bounds write. This vulnerability affects Firefox < 58. | Ubuntu_linux, Firefox | 9.8 | ||
| 2018-06-11 | CVE-2018-5095 | An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 8 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58. | Ubuntu_linux, Debian_linux, Firefox, Firefox_esr, Thunderbird, Enterprise_linux, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_workstation | 9.8 | ||
| 2018-11-16 | CVE-2018-18955 | In the Linux kernel 4.15.x through 4.19.x before 4.19.2, map_write() in kernel/user_namespace.c allows privilege escalation because it mishandles nested user namespaces with more than 5 UID or GID ranges. A user who has CAP_SYS_ADMIN in an affected user namespace can bypass access controls on resources outside the namespace, as demonstrated by reading /etc/shadow. This occurs because an ID transformation takes place properly for the namespaced-to-kernel direction but not for the... | Ubuntu_linux, Linux_kernel | 7.0 | ||
| 2019-02-28 | CVE-2018-18498 | A potential vulnerability leading to an integer overflow can occur during buffer size calculations for images when a raw value is used instead of the checked value. This leads to a possible out-of-bounds write. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. | Ubuntu_linux, Debian_linux, Firefox, Firefox_esr, Thunderbird, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_tus, Enterprise_linux_workstation | 9.8 | ||
| 2019-02-28 | CVE-2018-18497 | Limitations on the URIs allowed to WebExtensions by the browser.windows.create API can be bypassed when a pipe in the URL field is used within the extension to load multiple pages as a single argument. This could allow a malicious WebExtension to open privileged about: or file: locations. This vulnerability affects Firefox < 64. | Ubuntu_linux, Firefox | 6.5 | ||
| 2019-02-28 | CVE-2018-18495 | 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. | Ubuntu_linux, Firefox | 6.5 | ||
| 2018-12-12 | CVE-2018-18397 | 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. | Ubuntu_linux, Linux_kernel, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_tus, Enterprise_linux_workstation, Openshift_container_platform, Virtualization_host | 5.5 | ||
| 2018-10-30 | CVE-2018-18281 | 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. | Ubuntu_linux, Debian_linux, Linux_kernel | 7.8 |
