| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-10-25 | CVE-2021-21703 | Out-of-bounds Write vulnerability in multiple products In PHP versions 7.3.x up to and including 7.3.31, 7.4.x below 7.4.25 and 8.0.x below 8.0.12, when running PHP FPM SAPI with main FPM daemon process running as root and child worker processes running as lower-privileged users, it is possible for the child processes to access memory shared with the main process and write to it, modifying it in a way that would cause the root process to conduct invalid memory reads and writes, which can be used to escalate privileges from local unprivileged user to the root user. | 7.0 |
| 2021-07-30 | CVE-2021-32610 | Link Following vulnerability in multiple products In Archive_Tar before 1.4.14, symlinks can refer to targets outside of the extracted archive, a different vulnerability than CVE-2020-36193. | 7.1 |
| 2021-02-15 | CVE-2021-21702 | NULL Pointer Dereference vulnerability in multiple products In PHP versions 7.3.x below 7.3.27, 7.4.x below 7.4.15 and 8.0.x below 8.0.2, when using SOAP extension to connect to a SOAP server, a malicious SOAP server could return malformed XML data as a response that would cause PHP to access a null pointer and thus cause a crash. | 7.5 |
| 2021-01-18 | CVE-2020-36193 | Link Following vulnerability in multiple products Tar.php in Archive_Tar through 1.4.11 allows write operations with Directory Traversal due to inadequate checking of symbolic links, a related issue to CVE-2020-28948. | 7.5 |
| 2020-11-19 | CVE-2020-28949 | Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other stream-wrapper attack (such as file:// to overwrite files) can still succeed. | 7.8 |
| 2020-11-19 | CVE-2020-28948 | Deserialization of Untrusted Data vulnerability in multiple products Archive_Tar through 1.4.10 allows an unserialization attack because phar: is blocked but PHAR: is not blocked. | 7.8 |
| 2020-04-27 | CVE-2020-7067 | Out-of-bounds Read vulnerability in multiple products In PHP versions 7.2.x below 7.2.30, 7.3.x below 7.3.17 and 7.4.x below 7.4.5, if PHP is compiled with EBCDIC support (uncommon), urldecode() function can be made to access locations past the allocated memory, due to erroneously using signed numbers as array indexes. | 7.5 |
| 2020-04-01 | CVE-2020-7065 | Out-of-bounds Write vulnerability in multiple products In PHP versions 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using mb_strtolower() function with UTF-32LE encoding, certain invalid strings could cause PHP to overwrite stack-allocated buffer. | 8.8 |
| 2020-02-27 | CVE-2020-7062 | NULL Pointer Dereference vulnerability in multiple products In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when using file upload functionality, if upload progress tracking is enabled, but session.upload_progress.cleanup is set to 0 (disabled), and the file upload fails, the upload procedure would try to clean up data that does not exist and encounter null pointer dereference, which would likely lead to a crash. | 7.5 |
| 2020-02-12 | CVE-2011-3336 | Resource Exhaustion vulnerability in multiple products regcomp in the BSD implementation of libc is vulnerable to denial of service due to stack exhaustion. | 7.5 |
