Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Infinite loop (CVE-ID: CVE-2018-11813)
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.
2) Out-of-bounds read (CVE-ID: CVE-2018-14498)
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.
3) Buffer overflow (CVE-ID: CVE-2020-14152)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack or disclose sensitive information.
The vulnerability exists due to a boundary error in "jpeg_mem_available()" function in "jmemnobs.c" file in djpeg. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger memory corruption and gain access to sensitive information or cause a denial of service condition on the target system.
4) Stack-based buffer overflow (CVE-ID: CVE-2020-17541)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the in the "transform" component in Libjpeg-turb. A remote attacker can create a specially crafted JPEG image, pass it to the affected aplication, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
