Description
This security bulletin contains information about 6 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2016-10092)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/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 vulnerability exists due to heap-based buffer overflow in the readContigStripsIntoBuffer function in tif_unix.c when processing malicious input. A remote attacker can send a specially crafted image, trigger memory corruption and cause the service to crash.
2) Memory corruption (CVE-ID: CVE-2016-10093)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/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 vulnerability exists due to integer overflow in tools/tiffcp.c when processing malicious input. A remote attacker can send a specially crafted image, trigger heap-based buffer overflow and cause the service to crash.
3) Off-by-one error (CVE-ID: CVE-2016-10094)
CWE-ID: CWE-193 - Off-by-one Error
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/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 vulnerability exists due to off-by-one error in the t2p_readwrite_pdf_image_tile function in tools/tiff2pdf.c when processing malicious input. A remote attacker can send a specially crafted image and cause the service to crash.
4) Out-of-bounds read (CVE-ID: CVE-2016-6223)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition.
The vulnerability exists due to out-of-bounds read condition by the TIFFReadRawStrip1 and TIFFReadRawTile1 functions, as defined in the tif_read.c source code file. A remote attacker can trick the victim into opening or executing a file that submits malicious input and cause a DoS condition or possibly access sensitive information.
5) Uncontrolled memory allocation (CVE-ID: CVE-2017-12944)
CWE-ID: CWE-789 - Uncontrolled Memory Allocation
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 TIFFReadDirEntryArray function in tif_read.c due to mishandling memory allocation for short files. A remote attacker can trigger memory corruption and cause the service to crash.
6) NULL pointer dereference (CVE-ID: CVE-2018-19210)
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:L/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to cause DoS condition.
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 or executing a file that submits malicious input, trigger a NULL pointer dereference and cause the service to crash.
