Related CVEs: * CVE-2023-30608: A flaw was found in sqlparse. The SQL parser contains a regular expression vulnerable to a Regular Expression Denial of Service (ReDoS). The vulnerability may lead to a denial of service (DoS). * CVE-2023-31047: A bypass of validation flaw was found in python-django. When uploading multiple files using one form field, an attacker could upload multiple files without validation due to the server only validating the last file uploaded.

gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client. The unbounded memory buffering bugs: - The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb. - HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse. - gRPC’s metadata overflow check was performed per frame, so ...

Adobe Dimension version 3.4.9 is affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Microsoft has patched a total of 74 flaws in its software as part of the company's Patch Tuesday updates for August 2023, down from the voluminous 132 vulnerabilities the company fixed last month.

The cryptocurrency wallet entropy seeding mechanism used in Libbitcoin Explorer 3.0.0 through 3.6.0 is weak, aka the Milk Sad issue. The use of an mt19937 Mersenne Twister PRNG restricts the internal entropy to 32 bits regardless of settings. This allows remote attackers to recover any wallet private keys generated from "bx seed" entropy output and steal funds. (Affected users need to move funds to a secure new cryptocurrency wallet.) NOTE: the vendor's position is that there was sufficient documentation advising against "bx seed" but others disagree. NOTE: this was exploited in the wild in June and July 2023.

Dangerzone is software for converting potentially dangerous PDFs, office documents, or images to safe PDFs. The Dangerzone CLI (`dangerzone-cli` command) logs output from the container where the file sanitization takes place, to the user's terminal. Prior to version 0.4.2, if the container is compromised and can return attacker-controlled strings, then the attacker may be able to spoof messages in the user's terminal or change the window title. Besides logging output from containers, it also logs the names of the files it sanitizes. If these files contain ANSI escape sequences, then the same issue applies. Dangerzone is predominantly a GUI application, so this issue should leave most of our users unaffected. Nevertheless, we always suggest updating to the newest version. This issue is fixed in Dangerzone 0.4.2.
