Amazon Linux 2022 : php8.1 (ALAS2022-2022-243)

critical Nessus Plugin ID 168584

Language:

Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

The version of php8.1 installed on the remote host is prior to 8.1.12-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-243 advisory.

- In PHP versions 8.1.x below 8.1.8, when fileinfo functions, such as finfo_buffer, due to incorrect patch applied to the third party code from libmagic, incorrect function may be used to free allocated memory, which may lead to heap corruption. (CVE-2022-31627)

- In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the phar uncompressor code would recursively uncompress quines gzip files, resulting in an infinite loop. (CVE-2022-31628)

- In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site attackers to set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications. (CVE-2022-31629)

- In PHP versions prior to 7.4.33, 8.0.25 and 8.2.12, 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. (CVE-2022-31630)

- 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. (CVE-2022-37454)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update php8.1' to update your system.
