Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU29110

Risk: Medium

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2017-7544

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.

The vulnerability exists due to improper length computation of the allocated data of an ExifMnote entry within the exif_data_save_data_entry() function in libexif/exif-data.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.

Mitigation

Install updates from vendor's repository.
