CVE-2023-4806 – Glibc: potential use-after-free in getaddrinfo()
https://notcve.org/view.php?id=CVE-2023-4806
A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags. Se encontró una falla en glibc. • http://www.openwall.com/lists/oss-security/2023/10/03/4 http://www.openwall.com/lists/oss-security/2023/10/03/5 http://www.openwall.com/lists/oss-security/2023/10/03/6 http://www.openwall.com/lists/oss-security/2023/10/03/8 https://access.redhat.com/errata/RHSA-2023:5453 https://access.redhat.com/errata/RHSA-2023:5455 https://access.redhat.com/errata/RHSA-2023:7409 https://access.redhat.com/security/cve/CVE-2023-4806 https://bugzilla.redhat.com/sho • CWE-416: Use After Free •
CVE-2023-4527 – Glibc: stack read overflow in getaddrinfo in no-aaaa mode
https://notcve.org/view.php?id=CVE-2023-4527
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash. Se encontró una falla en glibc. Cuando se llama a la función getaddrinfo con la familia de direcciones AF_UNSPEC y el sistema está configurado con el modo no-aaaa a través de /etc/resolv.conf, una respuesta DNS a través de TCP de más de 2048 bytes puede potencialmente revelar el contenido de la pila de memoria a través de los datos de la dirección devuelta por la función, y puede provocar un crash. • http://www.openwall.com/lists/oss-security/2023/09/25/1 https://access.redhat.com/errata/RHSA-2023:5453 https://access.redhat.com/errata/RHSA-2023:5455 https://access.redhat.com/security/cve/CVE-2023-4527 https://bugzilla.redhat.com/show_bug.cgi?id=2234712 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4DBUQRRPB47TC3NJOUIBVWUGFHBJAFDL https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/DFG4P76UHHZEWQ26FWBXG76N2QLKKPZA https: • CWE-121: Stack-based Buffer Overflow CWE-125: Out-of-bounds Read •
CVE-2023-38039 – curl: out of heap memory issue due to missing limit on header quantity
https://notcve.org/view.php?id=CVE-2023-38039
When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API. However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory. Cuando curl recupera una respuesta HTTP, almacena los encabezados entrantes para que se pueda acceder a ellos más tarde a través de la API de encabezados libcurl. Sin embargo, curl no tenía un límite en cuanto a la cantidad o el tamaño de encabezados que aceptaría en una respuesta, lo que permitía que un servidor malicioso transmitiera una serie interminable de encabezados y, finalmente, provocara que curl se quedara sin memoria dinámica. A flaw was found in the Curl package. Curl allows a malicious server to stream an endless series of headers to a client due to missing limit on header quantity, eventually causing curl to run out of heap memory, which may lead to a crash. • https://github.com/Smartkeyss/CVE-2023-38039 http://seclists.org/fulldisclosure/2023/Oct/17 http://seclists.org/fulldisclosure/2024/Jan/34 http://seclists.org/fulldisclosure/2024/Jan/37 http://seclists.org/fulldisclosure/2024/Jan/38 https://hackerone.com/reports/2072338 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/5DCZMYODALBLVOXVJEN2LF2MLANEYL4F https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/M6KGKB2JNZVT276JYSKI6FV2VFJUGDOJ • CWE-770: Allocation of Resources Without Limits or Throttling •
