https://notcve.org/view.php?id=CVE-2022-40303
An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a segmentation fault. Se descubrió un problema en libxml2 antes de la versión 2.10.3. Al analizar un documento XML de varios gigabytes con la opción de analizador XML_PARSE_HUGE habilitada, varios contadores de enteros pueden desbordarse. • http://seclists.org/fulldisclosure/2022/Dec/21 http://seclists.org/fulldisclosure/2022/Dec/24 http://seclists.org/fulldisclosure/2022/Dec/25 http://seclists.org/fulldisclosure/2022/Dec/26 http://seclists.org/fulldisclosure/2022/Dec/27 https://gitlab.gnome.org/GNOME/libxml2/-/commit/c846986356fc149915a74972bf198abc266bc2c0 https://gitlab.gnome.org/GNOME/libxml2/-/tags/v2.10.3 https://security.netapp.com/advisory/ntap-20221209-0003 https://support.apple.com/kb/HT213531 https:/ • CWE-190: Integer Overflow or Wraparound •
CVSS: 9.8EPSS: 0%CPEs: 16EXPL: 1CVE-2022-32221 – curl: POST following PUT confusion
https://notcve.org/view.php?id=CVE-2022-32221
When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously was used to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST. Al realizar transferencias HTTP(S), libcurl podría usar erróneamente la devolución de llamada de lectura (`CURLOPT_READFUNCTION`) para solicitar datos para enviar, incluso cuando se haya configurado la opción `CURLOPT_POSTFIELDS`, si anteriormente se usó el mismo identificador para emitir un `PUT `solicitud que utilizó esa devolución de llamada. Esta falla puede sorprender a la aplicación y hacer que se comporte mal y envíe datos incorrectos o use memoria después de liberarla o algo similar en la solicitud "POST" posterior. • http://seclists.org/fulldisclosure/2023/Jan/19 http://seclists.org/fulldisclosure/2023/Jan/20 http://www.openwall.com/lists/oss-security/2023/05/17/4 https://hackerone.com/reports/1704017 https://lists.debian.org/debian-lts-announce/2023/01/msg00028.html https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20230110-0006 https://security.netapp.com/advisory/ntap-20230208-0002 https://support.apple.com/kb/HT213604 https://support.apple.com/k • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-440: Expected Behavior Violation CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 8.1EPSS: 0%CPEs: 18EXPL: 0CVE-2022-42915 – curl: HTTP proxy double-free
https://notcve.org/view.php?id=CVE-2022-42915
curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200 status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0. curl antes de la versión 7.86.0 tiene un double free. • http://seclists.org/fulldisclosure/2023/Jan/19 http://seclists.org/fulldisclosure/2023/Jan/20 https://curl.se/docs/CVE-2022-42915.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/37YEVVC6NAF6H7UHH6YAUY5QEVY6LIH2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HVU3IMZCKR4VE6KJ4GCWRL2ILLC6OV76 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Q27V5YYMXUVI6PRZQVECON32XPVWTKDK https://security.gentoo. • CWE-415: Double Free •

https://notcve.org/view.php?id=CVE-2022-35260
curl can be told to parse a `.netrc` file for credentials. If that file endsin a line with 4095 consecutive non-white space letters and no newline, curlwould first read past the end of the stack-based buffer, and if the readworks, write a zero byte beyond its boundary.This will in most cases cause a segfault or similar, but circumstances might also cause different outcomes.If a malicious user can provide a custom netrc file to an application or otherwise affect its contents, this flaw could be used as denial-of-service. Se puede indicar a curl que analice un archivo `.netrc` en busca de credenciales. Si ese archivo termina en una línea con 4095 letras de espacios consecutivos que no sean espacios en blanco y sin nueva línea, curl primero leerá más allá del final del búfer basado en pila y, si la lectura funciona, escribirá un byte cero más allá de su límite. En la mayoría de los casos, esto causará una falla de segmento o similar, pero las circunstancias también pueden causar resultados diferentes. • http://seclists.org/fulldisclosure/2023/Jan/19 http://seclists.org/fulldisclosure/2023/Jan/20 https://hackerone.com/reports/1721098 https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20230110-0006 https://support.apple.com/kb/HT213604 https://support.apple.com/kb/HT213605 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
