Description
This security bulletin contains information about 6 vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2016-3616)
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:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the cjpeg utility in libjpeg. A remote attacker can create a specially crafted image and perform a denial of service (DoS) attack.
2) Division by zero (CVE-ID: CVE-2018-11212)
CWE-ID: CWE-369 - Divide By Zero
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:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition.
The weakness exists due to division by zero error within the libjpeg library within the libjpeg-turbo in alloc_sarray() function of jmemmgr.c file. A remote attacker can pass a specially crafted file the to affected application and cause application to crash.
3) Input validation error (CVE-ID: CVE-2018-11213)
CWE-ID: CWE-20 - Improper input validation
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:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the get_text_gray_row() function in rdppm.c. A remote attacker can create a specially crafted image, trick the victim into opening it with software that uses the affected version of libjpeg, and perform a denial of service attack.
4) Input validation error (CVE-ID: CVE-2018-11214)
CWE-ID: CWE-20 - Improper input validation
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:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the get_text_rgb_row() function in rdppm.c. A remote attacker can create a specially crafted image, trick the victim into opening it with software that uses the affected version of libjpeg, and perform a denial of service attack.
5) Infinite loop (CVE-ID: CVE-2018-11813)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: 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/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in read_pixel() function in rdtarga.c when processing EOF (end-of-line) characters. A remote attacker can use a specially crafted image to consume all available system resources and cause denial of service conditions.
6) Out-of-bounds read (CVE-ID: CVE-2018-14498)
CWE-ID: CWE-125 - Out-of-bounds read
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 perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition when processing a crafted 8-bit BMP in which one or more of the color indices is out of range for the number of palette entries within the get_8bit_row in rdbmp.c. A remote attacker can create a specially crafted file, pass it to the application, trigger out-of-bounds read error and crash the affected application.
