CVE-2021-22898 – curl: TELNET stack contents disclosure
https://notcve.org/view.php?id=CVE-2021-22898
curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol. curl versiones 7.7 hasta 7.76.1 sufre de una divulgacion de información cuando la opción de línea de comandos "-t", conocida como "CURLOPT_TELNETOPTIONS" en libcurl, se usa para enviar pares de variables=contenido a servidores TELNET. Debido a un fallo en el analizador de opciones para el envío de variables NEW_ENV, podría hacer que libcurl pasara datos no inicializados de un búfer basado en la pila al servidor, resultando en una potencial divulgación de información interna confidencial al servidor que usaba un protocolo de red de texto sin cifrar A flaw was found in the way curl handled telnet protocol option for sending environment variables, which could lead to sending of uninitialized data from a stack-based buffer to the server. This issue leads to potentially revealing sensitive internal information to the server using a clear-text network protocol. • http://www.openwall.com/lists/oss-security/2021/07/21/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2021-22898.html https://github.com/curl/curl/commit/39ce47f219b09c380b81f89fe54ac586c8db6bde https://hackerone.com/reports/1176461 https://lists.apache.org/thread.html/rc713534b10f9daeee2e0990239fa407e2118e4aa9e88a7041177497c%40%3Cissues.guacamole.apache.org%3E https://lists.debian.org/debian-lts-announce/2021/08/msg00017.html https://lists.debian.org/debian-lts-ann • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-908: Use of Uninitialized Resource CWE-909: Missing Initialization of Resource •

CVE-2021-28652 – squid: denial of service issue in Cache Manager
https://notcve.org/view.php?id=CVE-2021-28652
An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cache Manager API access privilege. Se detectó un problema en Squid versiones anteriores a 4.15 y versiones 5.x anteriores a 5.0.6. • http://seclists.org/fulldisclosure/2023/Oct/14 http://www.openwall.com/lists/oss-security/2023/10/11/3 https://bugs.squid-cache.org/show_bug.cgi?id=5106 https://github.com/squid-cache/squid/security/advisories/GHSA-m47m-9hvw-7447 https://lists.debian.org/debian-lts-announce/2021/06/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LSQ3U54ZCNXR44QRPW3AV2VCS6K3TKCF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraprojec • CWE-401: Missing Release of Memory after Effective Lifetime •
