Description
This security bulletin contains information about 7 vulnerabilities.
1) Buffer over-read (CVE-ID: CVE-2017-17912)
CWE-ID: CWE-125 - Out-of-bounds read
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 heap-based buffer over-read in ReadNewsProfile in coders/tiff.c, in which LocaleNCompare reads heap data beyond the allocated region. A remote attacker can perform a denial of service attack.
2) Buffer over-read (CVE-ID: CVE-2017-17913)
CWE-ID: CWE-125 - Out-of-bounds read
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 stack-based buffer over-read in WriteWEBPImage in coders/webp.c, related to an incompatibility with libwebp versions, 0.5.0 and later, that use a different structure type. A remote attacker can perform a denial of service attack.
3) Out-of-bounds read (CVE-ID: CVE-2017-17915)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/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 heap-based buffer over-read in ReadMNGImage in coders/png.c, related to accessing one byte before testing whether a limit has been reached. A remote attacker can perform a denial of service attack.
4) Memory corruption (CVE-ID: CVE-2017-18219)
CWE-ID: CWE-789 - Uncontrolled Memory Allocation
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 unauthenicated attacker to cause DoS condition on the target system.
The weakness exists in the ReadOnePNGImage function due to memory allocation. A remote attacker can submit a specially crafted file, trigger memory corruption and cause the service to crash.
5) Memory corruption (CVE-ID: CVE-2017-18229)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 5.1 [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]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the ReadTIFFImage function due to memory allocation. A remote attacker can send a specially crafted file, trick the victim into opening it, trigger memory corruption and cause the service to crash.
6) NULL pointer dereference (CVE-ID: CVE-2017-18230)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 5.1 [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]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the ReadCINEONImage function due to NULL pointer dereference. A remote attacker can send a specially crafted file, trick the victim into opening it and cause the service to crash.
7) NULL pointer dereference (CVE-ID: CVE-2017-18231)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 5.1 [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]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the ReadEnhMetaFile function due to NULL pointer dereference. A remote attacker can send a specially crafted file, trick the victim into opnening it and cause the service to crash.
