1 CVE-2021-28702 269 Mem. Corr. 2021-10-06 2021-12-16
4.6
None Local Low Not required Partial Partial Partial
PCI devices with RMRRs not deassigned correctly Certain PCI devices in a system might be assigned Reserved Memory Regions (specified via Reserved Memory Region Reporting, "RMRR"). These are typically used for platform tasks such as legacy USB emulation. If such a device is passed through to a guest, then on guest shutdown the device is not properly deassigned. The IOMMU configuration for these devices which are not properly deassigned ends up pointing to a freed data structure, including the IO Pagetables. Subsequent DMA or interrupts from the device will have unpredictable behaviour, ranging from IOMMU faults to memory corruption.
2 CVE-2021-23978 Mem. Corr. 2021-02-26 2021-05-01
6.8
None Remote Medium Not required Partial Partial Partial
Mozilla developers reported memory safety bugs present in Firefox 85 and Firefox ESR 78.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8.
3 CVE-2021-20204 416 Exec Code Mem. Corr. 2021-05-06 2021-11-29
7.5
None Remote Low Not required Partial Partial Partial
A heap memory corruption problem (use after free) can be triggered in libgetdata v0.10.0 when processing maliciously crafted dirfile databases. This degrades the confidentiality, integrity and availability of third-party software that uses libgetdata as a library. This vulnerability may lead to arbitrary code execution or privilege escalation depending on input/skills of attacker.
4 CVE-2021-3407 415 Mem. Corr. 2021-02-23 2021-12-15
4.3
None Remote Medium Not required None None Partial
A flaw was found in mupdf 1.18.0. Double free of object during linearization may lead to memory corruption and other potential consequences.
5 CVE-2020-27815 787 Mem. Corr. 2021-05-26 2021-12-10
6.1
None Local Low Not required Partial Partial Complete
A flaw was found in the JFS filesystem code in the Linux Kernel which allows a local attacker with the ability to set extended attributes to panic the system, causing memory corruption or escalating privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
6 CVE-2020-22036 787 Overflow Mem. Corr. 2021-06-01 2021-11-05
6.8
None Remote Medium Not required Partial Partial Partial
A heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_intra at libavfilter/vf_bwdif.c, which might lead to memory corruption and other potential consequences.
7 CVE-2020-22032 787 Overflow Mem. Corr. 2021-05-27 2021-11-05
6.8
None Remote Medium Not required Partial Partial Partial
A heap-based Buffer Overflow vulnerability exists FFmpeg 4.2 at libavfilter/vf_edgedetect.c in gaussian_blur, which might lead to memory corruption and other potential consequences.
8 CVE-2020-22031 787 Overflow Mem. Corr. 2021-05-27 2021-11-05
6.8
None Remote Medium Not required Partial Partial Partial
A Heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 at libavfilter/vf_w3fdif.c in filter16_complex_low, which might lead to memory corruption and other potential consequences.
