Description
This security bulletin contains information about 10 vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2017-9935)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the t2p_write_pdf function in tools/tiff2pdf.c due to heap-based buffer overflow. A remote attacker can submit a specially crafted TIFF document, trigger out-of-bounds read in TIFFCleanup, an invalid free in TIFFClose or t2p_free, memory corruption in t2p_readwrite_pdf_image, or a double free in t2p_free and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may result in system compromise.
2) Improper input validation (CVE-ID: CVE-2017-11613)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.9 [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]
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.
3) NULL pointer dereference (CVE-ID: CVE-2017-18013)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 6.9 [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]
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.
4) Resource exhaustion (CVE-ID: CVE-2018-5784)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 6.9 [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]
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.
5) NULL pointer dereference (CVE-ID: CVE-2018-7456)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 6.9 [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]
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.
6) Heap-based buffer overflow (CVE-ID: CVE-2018-8905)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 8.7 [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]
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) Heap-based buffer over-read (CVE-ID: CVE-2018-10779)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
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.
8) Input validation error (CVE-ID: CVE-2018-10963)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.9 [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]
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.
9) Out-of-bounds write (CVE-ID: CVE-2018-18557)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
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.
10) Null pointer dereference (CVE-ID: CVE-2018-18661)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 0 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]
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.
