Description
This security bulletin contains information about 3 vulnerabilities.
1) Memory leak (CVE-ID: CVE-2021-40633)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:L/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 DoS attack on the target system.
The vulnerability exists due memory leak within the gif2rgb() function in util/gif2rgb.c. A remote attacker can force the application to leak memory and perform denial of service attack.
2) Heap-based buffer overflow (CVE-ID: CVE-2022-28506)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the DumpScreen2RGB() function in gif2rgb.c. A remote attacker can pass specially crafted file to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Buffer overflow (CVE-ID: CVE-2023-39742)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 a boundary error in getarg.c. A remote attacker can pass a specially crafted input to the application, trigger memory corruption and perform a denial of service (DoS) attack.
