CVSS: 8.1EPSS: 0%CPEs: 5EXPL: 1CVE-2022-31625 – Freeing unallocated memory in php_pgsql_free_params()
https://notcve.org/view.php?id=CVE-2022-31625
In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of service. En PHP versiones 7.4.x anteriores a 7.4.30, 8.0.x anteriores a 8.0.20 y 8.1.x anteriores a 8.1.7, cuando es usada la extensión de la base de datos Postgres, el suministro de parámetros no válidos a la consulta parametrizada puede conllevar que PHP intente liberar memoria usando datos no inicializados como punteros. Esto podría conllevar a una vulnerabilidad RCE o una denegación de servicio A vulnerability was found in PHP due to an uninitialized array in pg_query_params() function. When using the Postgres database extension, supplying invalid parameters to the parameterized query may lead to PHP attempting to free memory, using uninitialized data as pointers. • https://bugs.php.net/bug.php?id=81720 https://lists.debian.org/debian-lts-announce/2022/12/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3T4MMEEZYYAEHPQMZDFN44PHORJWJFZQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZZTZQKRGEYJT5UB4FGG3MOE72SQUHSL4 https://security.gentoo.org/glsa/202209-20 https://security.netapp.com/advisory/ntap-20220722-0005 https://www.debian.org/security/2022/dsa-5179 https://acce • CWE-590: Free of Memory not on the Heap CWE-763: Release of Invalid Pointer or Reference CWE-824: Access of Uninitialized Pointer •
CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 1CVE-2021-21708 – UAF due to php_filter_float() failing
https://notcve.org/view.php?id=CVE-2021-21708
In PHP versions 7.4.x below 7.4.28, 8.0.x below 8.0.16, and 8.1.x below 8.1.3, when using filter functions with FILTER_VALIDATE_FLOAT filter and min/max limits, if the filter fails, there is a possibility to trigger use of allocated memory after free, which can result it crashes, and potentially in overwrite of other memory chunks and RCE. This issue affects: code that uses FILTER_VALIDATE_FLOAT with min/max limits. En PHP versiones 7.4.x anteriores a 7.4.28, versiones 8.0.x anteriores a 8.0.16 y versiones 8.1.x anteriores a 8.1.3, cuando son usados funciones de filtrado con el filtro FILTER_VALIDATE_FLOAT y los límites mínimo/máximo, si el filtro falla, se presenta la posibilidad de que sea activado el uso de la memoria asignada después de liberarla, lo que puede resultar en un bloqueo, y potencialmente la sobreescritura de otros trozos de memoria y RCE. Este problema afecta a: el código que usa FILTER_VALIDATE_FLOAT con límites mín/máx. A flaw was found in PHP. • https://bugs.php.net/bug.php?id=81708 https://security.gentoo.org/glsa/202209-20 https://security.netapp.com/advisory/ntap-20220325-0004 https://access.redhat.com/security/cve/CVE-2021-21708 https://bugzilla.redhat.com/show_bug.cgi?id=2055879 • CWE-416: Use After Free •

zend_hash_del_key_or_index in zend_hash.c in PHP before 4.4.3 and 5.x before 5.1.3 can cause zend_hash_del to delete the wrong element, which prevents a variable from being unset even when the PHP unset function is called, which might cause the variable's value to be used in security-relevant operations. • ftp://patches.sgi.com/support/free/security/advisories/20060701-01-U http://archives.neohapsis.com/archives/fulldisclosure/2006-08/0166.html http://cvs.php.net/viewcvs.cgi/Zend/zend_hash.c?hideattic=0&r1=1.87.4.8.2.1&r2=1.87.4.8.2.2 http://cvs.php.net/viewcvs.cgi/Zend/zend_hash.c?hideattic=0&view=log http://rhn.redhat.com/errata/RHSA-2006-0549.html http://secunia.com/advisories/19927 http://secunia.com/advisories/21031 http://secunia.com/advisories/21050 •
