Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Use-after-free error

EUVDB-ID: #VU13498

Risk: High

CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-12882

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.

The vulnerability exists due to use-after-free error when the exif_read_from_impl function, as defined in the ext/exif/exif.c source code file, closes a stream that it is not responsible for closing. A remote unauthenticated attacker can trick the victim into opening a specially crafted file that submits malicious .jpeg input, trigger memory corruption and cause the service to crash or execute arbitrary code with elevated privileges.

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

EUVDB-ID: #VU13915

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-14883

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

Exploit availability: No

Description

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

The weakness exists due to integer overflow when processing exif_read_data in any 32-bit system. A remote attacker can trigger heap-based buffer overflow in exif_thumbnail_extract of exif.c and cause the service to crash.
