CVSS: 8.1EPSS: 0%CPEs: 3EXPL: 1CVE-2023-0568 – Array overrun in common path resolve code
https://notcve.org/view.php?id=CVE-2023-0568
In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, core path resolution function allocate buffer one byte too small. When resolving paths with lengths close to system MAXPATHLEN setting, this may lead to the byte after the allocated buffer being overwritten with NUL value, which might lead to unauthorized data access or modification. A vulnerability was found in PHP. This security issue occurs because the core path resolution function allocates a buffer one byte small. Resolving paths with lengths close to the system MAXPATHLEN setting may lead to the byte after the allocated buffer being overwritten with a NULL value, which might lead to unauthorized data access or modification. • https://bugs.php.net/bug.php?id=81746 https://security.netapp.com/advisory/ntap-20230517-0001 https://access.redhat.com/security/cve/CVE-2023-0568 https://bugzilla.redhat.com/show_bug.cgi?id=2170770 • CWE-131: Incorrect Calculation of Buffer Size CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-0662 – DoS vulnerability when parsing multipart request body
https://notcve.org/view.php?id=CVE-2023-0662
In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, excessive number of parts in HTTP form upload can cause high resource consumption and excessive number of log entries. This can cause denial of service on the affected server by exhausting CPU resources or disk space. A vulnerability was found in PHP. This security flaw occurs when the request body parsing in PHP allows any unauthenticated attacker to consume a large amount of CPU time and trigger excessive logging. A large amount of CPU time required for processing requests can block all available worker processes and significantly delay or slow the processing of legitimate user requests. • https://github.com/php/php-src/security/advisories/GHSA-54hq-v5wp-fqgv https://security.netapp.com/advisory/ntap-20230517-0001 https://access.redhat.com/security/cve/CVE-2023-0662 https://bugzilla.redhat.com/show_bug.cgi?id=2170761 • CWE-400: Uncontrolled Resource Consumption CWE-779: Logging of Excessive Data •
CVSS: 8.1EPSS: 0%CPEs: 3EXPL: 1CVE-2023-0567 – password_verify() always returns true for some invalid hashes
https://notcve.org/view.php?id=CVE-2023-0567
In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, password_verify() function may accept some invalid Blowfish hashes as valid. If such invalid hash ever ends up in the password database, it may lead to an application allowing any password for this entry as valid. A vulnerability was found in PHP. This security flaw occurs when malformatted BCrypt hashes that include a $ within their salt part trigger a buffer overread and may erroneously validate any password as valid. • https://bugs.php.net/bug.php?id=81744 https://github.com/php/php-src/security/advisories/GHSA-7fj2-8x79-rjf4 https://access.redhat.com/security/cve/CVE-2023-0567 https://bugzilla.redhat.com/show_bug.cgi?id=2170771 • CWE-328: Use of Weak Hash CWE-916: Use of Password Hash With Insufficient Computational Effort •
CVSS: 7.1EPSS: 0%CPEs: 3EXPL: 1CVE-2022-31630 – OOB read due to insufficient input validation in imageloadfont()
https://notcve.org/view.php?id=CVE-2022-31630
In PHP versions prior to 7.4.33, 8.0.25 and 8.1.12, when using imageloadfont() function in gd extension, it is possible to supply a specially crafted font file, such as if the loaded font is used with imagechar() function, the read outside allocated buffer will be used. This can lead to crashes or disclosure of confidential information. En versiones de PHP anteriores a 7.4.33, 8.0.25 y 8.2.12, cuando se usa la función imageloadfont() en la extensión gd, es posible proporcionar un archivo de fuente especialmente manipulado, como si la fuente cargada se usa con imagechar() función, se utilizará la lectura fuera del búfer asignado. Esto puede provocar fallos o divulgación de información confidencial. An out-of-bounds read flaw was found in PHP due to insufficient input validation in the imageloadfont() function. • https://bugs.php.net/bug.php?id=81739 https://access.redhat.com/security/cve/CVE-2022-31630 https://bugzilla.redhat.com/show_bug.cgi?id=2139280 • CWE-125: Out-of-bounds Read CWE-131: Incorrect Calculation of Buffer Size CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2022-37454
The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface. La implementación de referencia de Keccak XKCP SHA-3 versiones anteriores a fdc6fef, presenta un desbordamiento de enteros y un desbordamiento de búfer resultante que permite a atacantes ejecutar código arbitrario o eliminar las propiedades criptográficas esperadas. Esto ocurre en la interfaz de la función sponge A flaw was found in the Keccak XKCP SHA-3 reference implementation. The sponge function interface allows partial input data to be processed, and partial output to be produced. • https://csrc.nist.gov/projects/hash-functions/sha-3-project https://eprint.iacr.org/2023/331 https://github.com/XKCP/XKCP/security/advisories/GHSA-6w4m-2xhg-2658 https://lists.debian.org/debian-lts-announce/2022/10/msg00041.html https://lists.debian.org/debian-lts-announce/2022/11/msg00000.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3ALQ6BDDPX5HU5YBQOBMDVAA2TSGDKIJ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org&# • CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow •
