Description
This security bulletin contains information about 10 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) Heap-based buffer overflow (CVE-ID: CVE-2017-17095)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in tools/pal2rgb.c in pal2rgb due to heap-based buffer overflow. A remote attacker can trigger memory corruption and cause the service to crash.
3) Resource exhaustion (CVE-ID: CVE-2018-5784)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the TIFFSetDirectory function of tif_dir.c due to the declared number of directory entries is not validated against the actual number of directory entries. A remote attacker can submit a specially crafted tif file, trigger resource exhaustion 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 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.
6) 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.
7) 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.
8) 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.
9) Heap-based buffer overflow (CVE-ID: CVE-2018-15209)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to heap-based buffer overflow in ChopUpSingleUncompressedStrip in tif_dirread.c. A remote unauthenticated attacker can trick the victim into opening a specially crafted crafted TIFF file, trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.
10) Heap-based buffer overflow (CVE-ID: CVE-2018-16335)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to heap-based buffer overflow in newoffsets handling in ChopUpSingleUncompressedStrip in tif_dirread.c. A remote unauthenticated attacker can trick the victim into opening a specially crafted crafted TIFF file, trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.
