Description

This security bulletin contains information about 4 vulnerabilities.


1) Path traversal (CVE-ID: CVE-2010-4651)

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:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to write arbitrary files on the target system.

The weakness exists in util.c due to Path traversal. A remote attacker can trick the victim into opening a specially crafted file and create or overwrite arbitrary files via a filename that is specified with a .. (dot dot) or full pathname.

2) Resource exhaustion (CVE-ID: CVE-2014-9637)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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

The weakness exists due to memory consumption. A remote attacker can trick the victim into opening a specially crafted diff file and cause the service to crash.

3) Memory corruption (CVE-ID: CVE-2016-10713)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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

The weakness exists due to out-of-bounds access within pch_write_line() in pch.c. A local attacker can supply a specially crafted input, trigger memory corruption and cause the system to crash.

4) Improper input validation (CVE-ID: CVE-2018-1000156)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 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:U/U:Amber


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

The weakness exists in the EDITOR_PROGRAM invocation due to improper input validation. A remote attacker can send a specially crafted patch file and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.
