SB2017073122 - Multiple vulnerabilities in OpenExif

Description

This security bulletin contains information about 4 vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2017-14931)

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

CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

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

The vulnerability exists due to a boundary error when processing a crafted JPEG file. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

2) Heap-based buffer overflow (CVE-ID: CVE-2017-11115)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

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

The vulnerability exists due to a boundary error in The ExifJpegHUFFTable::deriveTable function in ExifHuffmanTable.cpp in OpenExif 2.1.4. A remote attacker can use a crafted jpg file. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) Out-of-bounds read (CVE-ID: CVE-2017-11117)

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

CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

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

The vulnerability exists due to a boundary error in The ExifImageFile::readDHT function in ExifImageFileRead.cpp in OpenExif 2.1.4. A remote attacker can perform a denial of service (heap-based buffer over-read and application crash) via a crafted jpg file.

4) Infinite loop (CVE-ID: CVE-2017-11118)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: 6.9 [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]

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

The ExifImageFile::readImage function in ExifImageFileRead.cpp in OpenExif 2.1.4 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a crafted jpg file.
