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-2020-15863 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.
3 CVE-2020-15708 732 Exec Code 2020-11-06 2020-11-12
4.6
None Local Low Not required Partial Partial Partial
Ubuntu's packaging of libvirt in 20.04 LTS created a control socket with world read and write permissions. An attacker could use this to overwrite arbitrary files or execute arbitrary code.
4 CVE-2020-15707 362 Exec Code Overflow Bypass 2020-07-29 2021-05-01
4.4
None Local Medium Not required Partial Partial Partial
Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions.
5 CVE-2020-15706 362 Exec Code Bypass 2020-07-29 2021-05-01
4.4
None Local Medium Not required Partial Partial Partial
GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2 version 2.04 and prior versions.
6 CVE-2020-14355 120 Exec Code Overflow 2020-10-07 2020-12-04
6.5
None Remote Low ??? Partial Partial Partial
Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution.
7 CVE-2020-11945 190 Exec Code Overflow 2020-04-23 2021-03-17
7.5
None Remote Low Not required Partial Partial Partial
An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials).
8 CVE-2020-11884 362 Exec Code 2020-04-29 2021-01-04
6.9
None Local Medium Not required Complete Complete Complete
In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution may occur because of a race condition, as demonstrated by code in enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur.
9 CVE-2020-9484 502 Exec Code 2020-05-20 2021-07-20
4.4
None Local Medium Not required Partial Partial Partial
When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed.
10 CVE-2020-7065 787 Exec Code Mem. Corr. 2020-04-01 2021-07-22
6.8
None Remote Medium Not required Partial Partial Partial
In PHP versions 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using mb_strtolower() function with UTF-32LE encoding, certain invalid strings could cause PHP to overwrite stack-allocated buffer. This could lead to memory corruption, crashes and potentially code execution.
11 CVE-2020-5963 269 DoS Exec Code 2020-06-25 2021-07-21

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.
