SB2019011102 - OpenSUSE Linux update for libraw

Description

This security bulletin contains information about 4 vulnerabilities.

1) Type confusion (CVE-ID: CVE-2018-5804)

CWE-ID: CWE-369 - Divide By Zero

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

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

The vulnerability exists due to type confusion error within the "identify()" function (internal/dcraw_common.cpp). A local attacker can supply a specially crafted input, trigger divide by zero error and cause the service to crash.

2) Infinite loop (CVE-ID: CVE-2018-5813)

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

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

The vulnerability allows a remote attacker to cause DoS condition.

The vulnerability exists due to due to improper parsing of files by the parse_minolta() function, as defined in the dcraw.c source code file of the affected software. A remote attacker can send trick the victim into accessing a file that submits malicious input, trigger an infinite loop condition that causes the affected software to crash or become unresponsive.

3) Infinite loop (CVE-ID: CVE-2018-5815)

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

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

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

The vulnerability exists due to integer overflow condition in the parse_qt()function, as defined in the internal/dcraw_common.cpp source code file in LibRaw versions prior to 0.18.12. A remote attacker can trick the victim into processing a specially crafted Apple QuickTime file, trigger an infinite loop condition and cause the service to crash.

4) Infinite loop (CVE-ID: CVE-2018-5816)

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

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

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

The vulnerability exists due to a divide by zero integer overflow condition in the identify() function, as defined in the internal/dcraw_common.cpp source code file in LibRaw versions prior to 0.18.12. A remote attacker can trick the victim into processing a specially crafted NOKIARAW file, trigger an infinite loop condition and cause the service to crash.
