Description

This security bulletin contains information about 5 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2017-11613)

CWE-ID: CWE-20 - Improper input validation

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


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

The weakness exists in the TIFFOpen function due to improper checking of td_imagelength during the TIFFOpen process. A remote attacker can cause the service to crash.

2) NULL pointer dereference (CVE-ID: CVE-2017-18013)

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:U/U:Clear


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

The vulnerability exists due to NULL pointer dereference error in tif_print.c within TIFFPrintDirectory() function. A remote attacker can trigger a NULL pointer dereference error and crash the affected application.


3) Input validation error (CVE-ID: CVE-2018-10963)

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


The vulnerability allows a remote attacker to cause denial of service conditions.

The vulnerability exists due to insufficient validation of user-supplied input processed by the TIFFWriteDirectorySec() function, as defined in the tif_dirwrite.c source code file. A remote attacker can trick the victim into opening a specially crafted file, trigger assertion failure and cause the application to crash.


4) NULL pointer dereference (CVE-ID: CVE-2018-7456)

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 unauthenticated attacker to cause DoS condition on the target system.

The vulnerability exists in the TIFFPrintDirectory function that is defined in the tif_print.c source code file due to NULL pointer dereference. A remote attacker can create a specially crafted TIFF file, trick the victim into opening it and cause the service to crash.


5) Heap-based buffer overflow (CVE-ID: CVE-2018-8905)

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

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


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

The weakness exists in the LZWDecodeCompat function due to insufficient validation of user-supplied input. A remote attacker can submit a specially crafted TIFF file, cause the service to crash or execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.
