openEuler 20.03 LTS SP1 update for php

1) Input validation error

EUVDB-ID: #VU47252

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-7070

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a spoofing attack.

The vulnerability exists in the way PHP parser handles cookies with percent character (e.g. '%'). A remote attacker can send a crafted HTTP request with a `__%48ost-` or `__%53ecure-` cookie that will be processed before other cookies sent in the same request. As a result, an attacker can set malicious `__Host-` cookie on a subdomain and bypass origin restrictions, imposed by browsers.

Successful exploitation of the vulnerability may allow an attacker to perform a spoofing attack.

Mitigation

Install updates from vendor's repository.

2) Cryptographic issues

EUVDB-ID: #VU47253

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-7069

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to the openssl_encrypt() function generates a wrong ciphertext and a wrong tag for AES-CCM for a 12 bytes IV. As a result, a 7-byte nonce is used instead of 12 bytes. A remote attacker can abuse such behavior and decrypt data.

Mitigation

Install updates from vendor's repository.

3) Out-of-bounds read

EUVDB-ID: #VU25110

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-7060

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition when using certain "mbstring" functions to convert multibyte encodings. A remote attacker can supply data that will cause function "mbfl_filt_conv_big5_wchar" to read past the allocated buffer, trigger out-of-bounds read error and read contents of memory on the system or crash the application.

Mitigation

Install updates from vendor's repository.
