Description

This security bulletin contains information about 5 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2016-6234)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The process_file function in lepton/jpgcoder.cc in Dropbox lepton 1.0 allows remote attackers to cause a denial of service (crash) via a crafted jpeg file.


2) Resource management error (CVE-ID: CVE-2016-6235)

CWE-ID: CWE-399 - Resource Management Errors

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


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The setup_imginfo_jpg function in lepton/jpgcoder.cc in Dropbox lepton 1.0 allows remote attackers to cause a denial of service (segmentation fault) via a crafted jpeg file.


3) Out-of-bounds read (CVE-ID: CVE-2016-6236)

CWE-ID: CWE-125 - Out-of-bounds read

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


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The setup_imginfo_jpg function in lepton/jpgcoder.cc in Dropbox lepton 1.0 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted jpeg file.
