When AdaCore Ada Web Server 25.0.0 is linked with GnuTLS, the default behaviour of AWS.Client is vulnerable to a man-in-the-middle attack because of lack of verification of an HTTPS server's certificate (unless the using program specifies a TLS configuration).

Attacker controlled files can be uploaded to arbitrary locations on the web server's filesystem by abusing a path traversal vulnerability.

Attackers can craft a malicious prompt that coerces the language model into executing arbitrary JavaScript in the context of the web page.

A stack-based buffer overflow vulnerability in gross 0.9.3 through 1.x before 1.0.4 allows remote attackers to trigger a denial of service (grossd daemon crash) or potentially execute arbitrary code in grossd via crafted SMTP transaction parameters that cause an incorrect strncat for a log entry.

The ACEManager component of ALEOS 4.16 and earlier does not

perform input sanitization during authentication, which could

potentially result in a Denial of Service (DoS) condition for

ACEManager without impairing other router functions. ACEManager

recovers from the DoS condition by restarting within ten seconds of

becoming unavailable.

Chromium: CVE-2023-6351 Use after free in libavif

Using the --fragment option in certain configuration setups OpenVPN version 2.6.0 to 2.6.6 allows an attacker to trigger a divide by zero behaviour which could cause an application crash, leading to a denial of service.

Summary An upper bound check issue in dsaVerify function allows an attacker to construct signatures that can be successfully verified by any public key, thus leading to a signature forgery attack.

Details In dsaVerify function, it checks whether the value of the signature is legal by calling function checkValue, namely, whether r and s are both in the interval [1, q - 1]. However, the second line of the checkValue function wrongly checks the upper bound of the passed parameters, since the value of b.cmp(q) can only be 0, 1 and -1, and it can never be greater than q.

In this way, although the values of s cannot be 0, an attacker can achieve the same effect as zero by setting its value to q, and then send (r, s) = (1, q) to pass the verification of any public key.

Impact All places in this project that involve DSA verification of user-input signatures will be affected by this vulnerability.

An issue was discovered in includes/page/Article.php in MediaWiki 1.36.x through 1.39.x before 1.39.5 and 1.40.x before 1.40.1. Deleted revision existence is leaked due to incorrect permissions being checked. This reveals that a given revision ID belonged to the given page title, and its timestamp, both of which are not supposed to be public information.

We will not publish our exploit for now; however, this buffer overflow is easily exploitable (by transforming it into a data-only attack), and other researchers might publish working exploits shortly after this coordinated disclosure. And they did, here are a couple:

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Versions of FreeRDP on the 3.x release branch before beta3 are subject to a Use-After-Free in processing RDPGFXCMDIDRESETGRAPHICS packets. If context->maxPlaneSize is 0, context->planesBuffer will be freed. However, without updating context->planesBuffer, this leads to a Use-After-Free exploit vector. In most environments this should only result in a crash. This issue has been addressed in version 3.0.0-beta3 and users of the beta 3.x releases are advised to upgrade. There are no known workarounds for this vulnerability.

DISPUTED An issue was discovered in TCG Accelerator in QEMU 4.2.0, allows local attackers to execute arbitrary code, escalate privileges, and cause a denial of service (DoS). Note: This is disputed as a bug and not a valid security issue by multiple third parties.

eprosima Fast DDS is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Prior to versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6, heap can be overflowed by providing a PIDPROPERTYLIST parameter that contains a CDR string with length larger than the size of actual content. In eprosima::fastdds::dds::ParameterPropertyListt::pushbackhelper, memcpy is called to first copy the octet'ized length and then to copy the data into properties.data. At the second memcpy, both data and size can be controlled by anyone that sends the CDR string to the discovery multicast port. This can remotely crash any Fast-DDS process. Versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6 contain a patch for this issue.

Prior to versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6, even after the fix at commit 3492270, malformed PIDPROPERTYLIST parameters cause heap overflow at a different program counter. This can remotely crash any Fast-DDS process. Versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6 contain a patch for this issue.
