1 CVE-2019-14835 120 Overflow 2019-09-17 2021-06-02
7.2
None Local Low Not required Complete Complete Complete
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
2 CVE-2019-6454 119 DoS Overflow 2019-03-21 2019-06-04
4.9
None Local Low Not required None None Complete
An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).
3 CVE-2019-5762 119 Exec Code Overflow 2019-02-19 2019-04-18

An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
7 CVE-2018-18501 119 Overflow Mem. Corr. 2019-02-05 2019-04-02
7.5
None Remote Low Not required Partial Partial Partial
Mozilla developers and community members reported memory safety bugs present in Firefox 64 and Firefox ESR 60.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
8 CVE-2018-18498 787 Overflow 2019-02-28 2020-08-24
7.5
None Remote Low Not required Partial Partial Partial
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.
9 CVE-2018-18493 119 Overflow 2019-02-28 2019-03-11
7.5
None Remote Low Not required Partial Partial Partial
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.
10 CVE-2018-17470 119 Overflow 2019-01-09 2019-01-15
4.3
None Remote Medium Not required None None Partial
A heap buffer overflow in GPU in Google Chrome prior to 70.0.3538.67 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.
11 CVE-2018-12547 119 Overflow 2019-02-11 2019-05-16
7.5
None Remote Low Not required Partial Partial Partial
In Eclipse OpenJ9, prior to the 0.12.0 release, the jio_snprintf() and jio_vsnprintf() native methods ignored the length parameter. This affects existing APIs that called the functions to exceed the allocated buffer. This functions were not directly callable by non-native user code.
12 CVE-2018-12405 119 Overflow Mem. Corr. 2019-02-28 2019-03-12

5.0
None Remote Low Not required None None Partial
A potential vulnerability was found in 32-bit builds where an integer overflow during the conversion of scripts to an internal UTF-16 representation could result in allocating a buffer too small for the conversion. This leads to a possible out-of-bounds write. *Note: 64-bit builds are not vulnerable to this issue.*. This vulnerability affects Firefox < 63, Firefox ESR < 60.3, and Thunderbird < 60.3.
