Description

This security bulletin contains information about 7 vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2018-20337)

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

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:P/U:Clear

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

The vulnerability exists due to stack-based buffer overflow in the parse_makernote function of dcraw_common.cpp. A remote attacker can trick the victim into opening a specially crafted input, trigger memory corruption and perform DoS attack.

2) NULL pointer dereference (CVE-ID: CVE-2018-20363)

CWE-ID: CWE-476 - NULL Pointer Dereference

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:P/U:Clear

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

The vulnerability exists due to a NULL pointer dereference error in libraw_cxx.cpp in. A remote attacker can trick the victim into opening a specially crafted input and perform a denial of service (DoS) attack.

3) NULL pointer dereference (CVE-ID: CVE-2018-20364)

CWE-ID: CWE-476 - NULL Pointer Dereference

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:P/U:Clear

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

The vulnerability exists due to a NULL pointer dereference error in libraw_cxx.cpp. A remote attacker can trick the victim into opening a specially crafted input and perform a denial of service (DoS) attack.

4) Heap-based buffer overflow (CVE-ID: CVE-2018-20365)

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

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:P/U:Clear

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

The vulnerability exists due to heap-based buffer overflow in libraw_cxx.cpp. A remote attacker can trick the victim into opening a specially crafted input, trigger memory corruption and perform DoS attack.

5) Infinite loop (CVE-ID: CVE-2018-5817)

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 perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in the unpacked_load_raw function of dcraw_common.cpp. A remote attacker can trick the victim into opening a specially crafted input and perform DoS attack.

6) Infinite loop (CVE-ID: CVE-2018-5818)

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 perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in the parse_rollei function of dcraw_common.cpp. A remote attacker can trick the victim into opening a specially crafted input and perform DoS attack.

7) Input validation error (CVE-ID: CVE-2018-5819)

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:L/SC:N/SI:N/SA:N/E:P/U:Clear

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

The vulnerability exists in the parse_sinar_ia function
of dcraw_common.cpp due to insufficient validation of user-supplied input. A remote attacker can trick the victim into opening a specially crafted input and cause the service to crash.
