Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Heap-based buffer over-read

EUVDB-ID: #VU12760

Risk: Low

CVSSv4.0: 1.2 [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]

CVE-ID: CVE-2017-14731

CWE-ID: CWE-126 - Buffer over-read

Exploit availability: No

Description

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

The weakness exists in ofx_proc_file in ofx_preproc.cpp due to a boundary error. A remote attacker can trick the victim into opening a specially crafted file, as demonstrated by an ofxdump call, trigger heap-based buffer over-read and cause the service to crash.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 26

libofx: before 0.9.10-5.fc26

https://bodhi.fedoraproject.org/updates/FEDORA-2018-4a2b875d6b


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Out-of-bounds write

EUVDB-ID: #VU8430

Risk: High

CVSSv4.0: 7.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2017-2816

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The weakness exists in the tag parsing functionality due to out-of-bounds write when handling malicious input. A remote attacker can trick the victim into opening a specially crafted OFX file, trigger stack-based buffer overflow and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install updates from vendor's repository.

Risk: High

CVSSv4.0: 7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2017-2920

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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