Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU57656
Risk: Low
CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2021-21703
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists in the way PHP handles shared memory access, when using PHP FPM SAPI with main FPM daemon process running as root and child worker processes running as lower-privileged users. A child process can access shared memory with the main process and write to it. As a result, it is possible to cause the root process to conduct invalid memory reads and writes with root privileges. A local user can trigger an out-of-bounds write error and execute arbitrary code on the system with root privileges.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Use-after-free
EUVDB-ID: #VU60707
Risk: Medium
CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2021-21708
CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the "php_filter_float()" function. A remote attacker can pass specially crafted input to the application that uses the affected PHP function, trigger a use-after-free error and crash the php-fpm process.

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
3) Input validation error
EUVDB-ID: #VU58331
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-21707
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to inject arbitrary XML code.
The vulnerability exists due to insufficient validation of user-supplied input within the simplexml_load_file() PHP function when processing NULL byte character (e.g. %00). A remote attacker can pass specially crafted URL to the application and bypass implemented security restrictions.

4) Security features bypass
EUVDB-ID: #VU67756
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2022-31629
CWE-ID:
CWE-254 - Security Features
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the way PHP handles HTTP variable names. A remote attacker can set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.

5) Infinite loop
EUVDB-ID: #VU67755
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-31628
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the phar uncompressor code when processing "quines" gzip files. A remote attacker can pass a specially crafted archive to the application, consume all available system resources and cause denial of service conditions.
