Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a Denial of Service (memory leak), aka TROVE-2020-004. This occurs in circpad_setup_machine_on_circ because a circuit-padding machine can be negotiated twice on the same circuit.

Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a Denial of Service (CPU consumption), aka TROVE-2020-002.

Bluetooth devices supporting BR/EDR v5.2 and earlier are vulnerable to impersonation attacks

Legacy pairing and secure-connections pairing authentication in Bluetooth BR/EDR Core Specification v5.2 and earlier may allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. An unauthenticated, adjacent attacker could impersonate a Bluetooth BR/EDR master or slave to pair with a previously paired remote device to successfully complete the authentication procedure without knowing the link key.

webkitgtk: Use-after-free issue in accessibility/AXObjectCache.cpp

WebKitGTK through 2.26.4 and WPE WebKit through 2.26.4 (which are the versions right before 2.28.0) contains a memory corruption issue (use-after-free) that may lead to arbitrary code execution. This issue has been fixed in 2.28.0 with improved memory handling.

qt: files placed by attacker can influence the working directory and lead to malicious code execution

Out of bounds write in Intel(R) PROSet/Wireless WiFi products on Windows 10 may allow an authenticated user to potentially enable denial of service via local access.

Improper initialization in the Intel(R) SGX SDK before v2.6.100.1 may allow an authenticated user to potentially enable escalation of privilege via local access.

bluez: Improper access control in subsystem could result in privilege escalation and DoS

Improper access control in subsystem for BlueZ before version 5.54 may allow an unauthenticated user to potentially enable escalation of privilege and denial of service via adjacent access

hw: L1D Cache Eviction Sampling

Cleanup errors in some data cache evictions for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

hw: Special Register Buffer Data Sampling (SRBDS)

Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

kernel: possible out of bounds write in skb_to_mamac of networking.c

In skb_to_mamac of networking.c, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed.

bash: BASH_CMD is writable in restricted bash shells

rbash in Bash before 4.4-beta2 did not prevent the shell user from modifying BASH_CMDS, thus allowing the user to execute any command with the permissions of the shell.

Potential recycling of random numbers used in cryptography exists within PuTTY before 0.71.

Multiple denial-of-service attacks that can be triggered by writing to the terminal exist in PuTTY versions before 0.71.

In PuTTY versions before 0.71 on Windows, local attackers could hijack the application by putting a malicious help file in the same directory as the executable.

A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification.

Windows 8.3 path equivalence handling flaw allows LibreLogo script execution

LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can execute arbitrary python commands contained with the document it is launched from. LibreOffice also has a feature where documents can specify that pre-installed scripts can be executed on various document script events such as mouse-over, etc. Protection was added to block calling LibreLogo from script event handers. However a Windows 8.3 path equivalence handling flaw left LibreOffice vulnerable under Windows that a document could trigger executing LibreLogo via a Windows filename pseudonym. This issue affects: Document Foundation LibreOffice 6.2 versions prior to 6.2.7; 6.3 versions prior to 6.3.1.
