Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU20920

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-3977

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the gif2rgb() function (util/gif2rgb.c) in giflib 5.1.2. A remote attacker can use background color index in a GIF 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.

Mitigation

Update the affected package giflib to the latest version.

2) Heap-based buffer overflow

EUVDB-ID: #VU75499

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-11490

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the DGifDecompressLine function in dgif_lib.c in GIFLIB because a certain "Private->RunningCode - 2" array index is not checked. A remote attacker can trigger a 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.

Mitigation

Update the affected package giflib to the latest version.

3) Division by zero

EUVDB-ID: #VU30817

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-15133

CWE-ID: CWE-369 - Divide By Zero

Exploit availability: No

Description

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

In GIFLIB before 2019-02-16, a malformed GIF file triggers a divide-by-zero exception in the decoder function DGifSlurp in dgif_lib.c if the height field of the ImageSize data structure is equal to zero.

Mitigation

Update the affected package giflib to the latest version.
