Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2018-12900)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to heap-based buffer overflow in the cpSeparateBufToContigBuf function in tiffcp.c. A remote unauthenticated attacker can trick the victim into opening a specially crafted TIFF file that can trigger memory corruption and cause the service to crash.
2) 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.
3) Null pointer dereference (CVE-ID: CVE-2018-18661)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to NULL pointer dereference in the function LZWDecode in the file tif_lzw.c. A remote attacker can trick the victim into opening a specially crafted input, trigger NULL pointer dereference and cause the service 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 over-read (CVE-ID: CVE-2018-10779)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the TIFFWriteScanline function in the tif_write.csource code file due to insufficient validation of user-supplied input. A local attacker can use the .bmp2tiff command to execute a specially crafted file, trigger heap-based buffer over-read and cause the service to crash.
6) 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.
7) Out-of-bounds write (CVE-ID: CVE-2018-18557)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to decoding of arbitrarily-sized JBIG into a buffer, ignoring the buffer size. A remote unauthenticated attacker can supply specially crafted input, trigger a tif_jbig.c JBIGDecode out-of-bounds write and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Buffer overflow (CVE-ID: CVE-2016-3186)
The vulnerability allows a remote attacker can cause DoS condition on the target system.The weakness exists in the gif2tiff.c due to buffer overflow. A remote attacker can submit a specially crafted GIF file and cause the service to crash.
9) Integer overflow (CVE-ID: CVE-2018-17100)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to int32 overflow when insufficient validation of user-supplied input processed by the multiply_ms() function, as defined in the tools/ppm2tiff.c source code file. A remote unauthenticated attacker can trick the victim into opening or executing an image file that submits malicious input to the targeted system. A successful exploit could trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.
10) Out-of-bounds read (CVE-ID: CVE-2018-17101)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to out-of-bounds read during insufficient validation of user-supplied input processed by the cpTags function, as defined in the tools/tiff2bw.c and tools/pal2rgb.c source code files. A remote unauthenticated attacker can trick the victim into opening or executing an image file that submits malicious input to the targeted system. A successful exploit could trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.
11) Assertion failure (CVE-ID: CVE-2017-13726)
The vulnerability allows a remote attacker to cause DoS condition.
The vulnerability exists due to a reachable assertion abort in the function TIFFWriteDirectorySec(), related to tif_dirwrite.c and a SubIFD tag when processing malicious input. A remote attacker can send specially crafted input, trigger assertion failure and cause the service to crash.
12) 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.
