Description

This security bulletin contains information about 2 vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2018-6758)

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

CVSSv4: 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


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the uwsgi_expand_path function due to stack-based buffer overflow. A remote attacker can request a specially crafted long directory path, trigger memory corruption and cause the service to crash.


2) Path traversal (CVE-ID: CVE-2018-7490)

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

CVSSv4: 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:P/U:Clear


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to improper file path validation when requesting a resource under the DOCUMENT_ROOT directory. A remote attacker can cause path traversal and gain access to potentially sensitive information.
