| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2019-02-28 | CVE-2018-12407 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products A buffer overflow occurs when drawing and validating elements with the ANGLE graphics library, used for WebGL content, when working with the VertexBuffer11 module. | 9.8 |
| 2019-02-28 | CVE-2018-18492 | Use After Free vulnerability in multiple products 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. | 9.8 |
| 2019-02-28 | CVE-2018-18493 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products 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. | 9.8 |
| 2019-02-28 | CVE-2018-18498 | Integer Overflow or Wraparound vulnerability in multiple products 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. | 9.8 |
| 2019-02-26 | CVE-2019-9169 | Out-of-bounds Read vulnerability in multiple products In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-based buffer over-read via an attempted case-insensitive regular-expression match. | 9.8 |
| 2019-02-24 | CVE-2019-8375 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products The UIProcess subsystem in WebKit, as used in WebKitGTK through 2.23.90 and WebKitGTK+ through 2.22.6 and other products, does not prevent the script dialog size from exceeding the web view size, which allows remote attackers to cause a denial of service (Buffer Overflow) or possibly have unspecified other impact, related to UIProcess/API/gtk/WebKitScriptDialogGtk.cpp, UIProcess/API/gtk/WebKitScriptDialogImpl.cpp, and UIProcess/API/gtk/WebKitWebViewGtk.cpp, as demonstrated by GNOME Web (aka Epiphany). | 9.8 |
| 2019-02-22 | CVE-2019-9020 | Use After Free vulnerability in multiple products An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. | 9.8 |
| 2019-02-22 | CVE-2019-9021 | Out-of-bounds Read vulnerability in multiple products An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. | 9.8 |
