The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.
In imap_scan_tree_recursive in Claws Mail through 3.17.6, a malicious IMAP server can trigger stack consumption because of unlimited recursion into subdirectories during a rebuild of the folder tree.
In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to missing input sanitation in rdpegfx channel. All FreeRDP clients are affected. The input rectangles from the server are not checked against local surface coordinates and blindly accepted. A malicious server can send data that will crash the client later on (invalid length arguments to a `memcpy`) This has been fixed in 2.2.0. As a workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto
LibEtPan through 1.9.4, as used in MailCore 2 through 0.6.3 and other products, has a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a "begin TLS" response, the client reads additional data (e.g., from a meddler-in-the-middle attacker) and evaluates it in a TLS context, aka "response injection."
Heap buffer overflow in WebAudio in Google Chrome prior to 84.0.4147.89 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
Heap buffer overflow in Skia in Google Chrome prior to 84.0.4147.89 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
Inappropriate implementation in iframe sandbox in Google Chrome prior to 84.0.4147.89 allowed a remote attacker to bypass navigation restrictions via a crafted HTML page.
Insufficient policy enforcement in CSP in Google Chrome prior to 84.0.4147.89 allowed a remote attacker to bypass content security policy via a crafted HTML page.
