1 CVE-2020-29385 835 DoS Exec Code 2020-12-26 2021-03-22
4.3
None Remote Medium Not required None None Partial
GNOME gdk-pixbuf (aka GdkPixbuf) before 2.42.2 allows a denial of service (infinite loop) in lzw.c in the function write_indexes. if c->self_code equals 10, self->code_table[10].extends will assign the value 11 to c. The next execution in the loop will assign self->code_table[11].extends to c, which will give the value of 10. This will make the loop run infinitely. This bug can, for example, be triggered by calling this function with a GIF image with LZW compression that is crafted in a special way.
2 CVE-2020-24606 20 DoS 2020-08-24 2021-07-21
7.1
None Remote Medium Not required None None Complete
Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF.
3 CVE-2020-15863 787 DoS Exec Code Overflow 2020-07-28 2021-01-04
4.4
None Local Medium Not required Partial Partial Partial
hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555.
4 CVE-2020-12829 190 DoS Overflow 2020-08-31 2020-12-14
2.1
None Local Low Not required None None Partial
In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write() callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in hw/display/sm501.c on the host, resulting in a denial of service.
5 CVE-2020-11655 665 DoS 2020-04-09 2021-07-22
5.0
None Remote Low Not required None None Partial
SQLite through 3.31.1 allows attackers to cause a denial of service (segmentation fault) via a malformed window-function query because the AggInfo object's initialization is mishandled.
6 CVE-2020-5973 20 DoS 2020-06-30 2021-07-21
2.1
None Local Low Not required None None Partial
NVIDIA Virtual GPU Manager and the guest drivers contain a vulnerability in vGPU plugin, in which there is the potential to execute privileged operations, which may lead to denial of service. This affects vGPU version 8.x (prior to 8.4), version 9.x (prior to 9.4) and version 10.x (prior to 10.3).
7 CVE-2020-5967 362 DoS 2020-06-25 2020-07-13
1.9
None Local Medium Not required None None Partial
NVIDIA Linux GPU Display Driver, all versions, contains a vulnerability in the UVM driver, in which a race condition may lead to a denial of service.
8 CVE-2020-5963 269 DoS Exec Code 2020-06-25 2021-07-21
4.6
None Local Low Not required Partial Partial Partial
NVIDIA Windows GPU Display Driver, all versions, contains a vulnerability in the Inter Process Communication APIs, in which improper access control may lead to code execution, denial of service, or information disclosure.
