Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU68886
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-31630
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the imageloadfont() function. A remote attacker can pass specially crafted data to the web application, trigger an out-of-bounds read error and read contents of memory on the system.
MitigationUpdate the affected package php80/php81.
Vulnerable software versionsSlackware Linux: 15.0
php81: before 8.1.12

2) Integer overflow
EUVDB-ID: #VU68887
Risk: High
CVSSv4.0: 8.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
CVE-ID: CVE-2022-37454
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the Keccak XKCP SHA-3 reference implementation. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system or eliminate expected cryptographic properties.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package php80/php81.
