#buffer_overflow

SOUND4 LinkAndShare Transmitter version 1.1.2 suffers from a format string memory leak and stack buffer overflow vulnerability because it fails to properly sanitize user supplied input when calling the getenv() function from MSVCR120.DLL resulting in a crash overflowing the memory stack and leaking sensitive information. The attacker can abuse the username environment variable to trigger and potentially execute code on the affected system.

The OpenSSL Project has released fixes to address several security flaws, including a high-severity bug in the open source encryption toolkit that could potentially expose users to malicious attacks. Tracked as CVE-2023-0286, the issue relates to a case of type confusion that may permit an adversary to "read memory contents or enact a denial-of-service," the maintainers said in an advisory. The

Delta Electronics DIAScreen versions 1.2.1.23 and prior are vulnerable to a buffer overflow through improper restrictions of operations within memory, which could allow an attacker to remotely execute arbitrary code.

The application suffers from a format string memory leak and stack buffer overflow vulnerability because it fails to properly sanitize user supplied input when calling the getenv() function from MSVCR120.DLL resulting in a crash overflowing the memory stack and leaking sensitive information. The attacker can abuse the username environment variable to trigger and potentially execute code on the affected system.

A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. The read buffer overrun might result in a crash which could lead to a denial of service attack. In theory it could also result in the disclosure of private memory contents (such as private keys, or sensitive plaintext) although we are not aware of any working exploit leading to memory contents disclosure as of the time of release of this advisory. In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects.

A NULL pointer can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail. There is a missing check for the return value from the initialization function which later leads to invalid usage of the digest API most likely leading to a crash. The unavailability of an algorithm can be caused by using FIPS enabled configuration of providers or more commonly by not loading the legacy provider. PKCS7 data is processed by the SMIME library calls and also by the time stamp (TS) library calls. The TLS implementation in OpenSSL does not call these functions however third party applications would be affected if they call these functions to verify signatures on untrusted data.

By Deeba Ahmed The refutation came days after Europe and North America were rattled by ESXiArgs Ransomware attacks. This is a post from HackRead.com Read the original post: VMware Disputes Old Flaws at Root of ESXiArgs Ransomware Attacks

VMware on Monday said it found no evidence that threat actors are leveraging an unknown security flaw, i.e., a zero-day, in its software as part of an ongoing ransomware attack spree worldwide. "Most reports state that End of General Support (EoGS) and/or significantly out-of-date products are being targeted with known vulnerabilities which were previously addressed and disclosed in VMware
