CVSS: 9.8EPSS: 0%CPEs: 14EXPL: 8CVE-2023-38545 – curl: heap based buffer overflow in the SOCKS5 proxy handshake
https://notcve.org/view.php?id=CVE-2023-38545
This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due to this bug, the local variable that means "let the host resolve the name" could get the wrong value during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target buffer instead of copying just the resolved address there. The target buffer being a heap based buffer, and the host name coming from the URL that curl has been told to operate with. Esta falla hace que curl desborde un búfer basado en el protocolo de enlace del proxy SOCKS5. Cuando se le pide a curl que pase el nombre de host al proxy SOCKS5 para permitir que resuelva la dirección en lugar de que lo haga curl mismo, la longitud máxima que puede tener el nombre de host es 255 bytes. Si se detecta que el nombre de host es más largo, curl cambia a la resolución de nombres local y en su lugar pasa solo la dirección resuelta. • https://github.com/d0rb/CVE-2023-38545 https://github.com/vanigori/CVE-2023-38545-sample https://github.com/UTsweetyfish/CVE-2023-38545 https://github.com/fatmo666/CVE-2023-38545-libcurl-SOCKS5-heap-buffer-overflow https://github.com/imfht/CVE-2023-38545 https://github.com/bcdannyboy/CVE-2023-38545 https://github.com/dbrugman/CVE-2023-38545-POC https://github.com/Yang-Shun-Yu/CVE-2023-38545 http://seclists.org/fulldisclosure/2024/Jan/34 http://seclists.org/fulldisclosure • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-38159
Windows Graphics Component Elevation of Privilege Vulnerability Vulnerabilidad de elevación de privilegios en Windows Graphics Component This vulnerability allows local attackers to escalate privileges on affected installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of GPU mapped memory. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. • https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-38159 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-591: Sensitive Data Storage in Improperly Locked Memory •
