CVSS: 5.9EPSS: 0%CPEs: 29EXPL: 0CVE-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.

CVSS: 6.5EPSS: 0%CPEs: 38EXPL: 1CVE-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 •

https://notcve.org/view.php?id=CVE-2023-4813
A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. Se encontró una falla en glibc. En una situación poco común, la función gaih_inet puede utilizar memoria que se ha liberado, lo que provoca un bloqueo de la aplicación. • 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-2023-4813 https://bugzilla.redhat.com/show_bug.cgi?id=2237798 https://security.netapp.com/advisory/ntap-20231110-0003 • CWE-416: Use After Free •

end_pattern (called from internal_fnmatch) in the GNU C Library (aka glibc or libc6) before 2.22 might allow context-dependent attackers to cause a denial of service (application crash), as demonstrated by use of the fnmatch library function with the **(!() pattern. NOTE: this is not the same as CVE-2015-8984; also, some Linux distributions have fixed CVE-2015-8984 but have not fixed this additional fnmatch issue. • https://security.netapp.com/advisory/ntap-20230731-0009 https://sourceware.org/bugzilla/show_bug.cgi?id=18036 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
