Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2017-11613)
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)
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)
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)
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)
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.
