Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Man-in-the-middle attack

EUVDB-ID: #VU13112

Risk: Low

CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-3152

CWE-ID: CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')

Exploit availability: No

Description

The vulnerability allows a remote attacker to conduct man-in-the-middle attack on the target system.

The vulnerability exists due to use of the --ssl option to mean that SSL is optional. A remote attacker can conduct man-in-the-middle attack, intercept of the communication channel between the affected app and spoof servers via a cleartext-downgrade attack, aka a "BACKRONYM" attack.

Mitigation

2) Input validation error

EUVDB-ID: #VU32405

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-5589

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The phar_convert_to_other function in ext/phar/phar_object.c in PHP before 5.4.43, 5.5.x before 5.5.27, and 5.6.x before 5.6.11 does not validate a file pointer before a close operation, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted TAR archive that is mishandled in a Phar::convertToData call.

3) Stack-based buffer overflow

EUVDB-ID: #VU32406

Risk: Medium

CVSSv3.1: 6.4 [AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-5590

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the phar_fix_filepath function in ext/phar/phar.c when processing a large length value, as demonstrated by mishandling of an e-mail attachment by the imap PHP extension. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

EUVDB-ID: #VU40516

Risk: Medium

CVSSv3.1: 6.9 [AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N/E:U/RL:U/RC:C]

CVE-ID: CVE-2015-6833

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in the PharData class in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12. A remote authenticated attacker can send a specially crafted HTTP request and remote attackers to write to arbitrary files via a . (dot dot) in a ZIP archive entry that is mishandled during an extractTo call.
