Description
This security bulletin contains information about 3 vulnerabilities.
1) Infinite loop (CVE-ID: CVE-2018-10177)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/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 ReadOneMNGImage function of the coders/png.c file due to infinite loop. A remote attacker can trick the victim into opening a specially crafted mng file and cause the service to crash.
2) Heap-based buffer over-read (CVE-ID: CVE-2018-8960)
CWE-ID: CWE-126 - Buffer over-read
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 ReadTIFFImage function in coders/tiff.c due to improper restriction of memory allocation. A remote attacker can trigger heap-based buffer over-read and cause the service to crash.
3) Heap-based buffer over-read (CVE-ID: CVE-2018-9135)
CWE-ID: CWE-126 - Buffer over-read
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 IsWEBPImageLossless in coders/webp.c due to heap-based buffer over-read. A remote attacker can cause the service to crash.
