Description
This security bulletin contains information about 6 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2020-21680)
CWE-ID: CWE-121 - Stack-based buffer overflow
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:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when converting a xfig file into pict2e format. A remote attacker can trigger a stack-based buffer overflow and crash the application.
2) Buffer overflow (CVE-ID: CVE-2020-21682)
CWE-ID: CWE-120 - Buffer overflow
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:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the set_fill component in genge.c when converting a xfig file into ge format. A remote attacker can pass a specially crafted file to the application and crash it.
3) Buffer overflow (CVE-ID: CVE-2020-21683)
CWE-ID: CWE-120 - Buffer overflow
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:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the shade_or_tint_name_after_declare_color() function in fig2dev/dev/genpstricks.c when converting a xfig file into pstricks format. A remote attacker can pass a specially crafted file to the application and crash it.
4) Incorrect calculation (CVE-ID: CVE-2025-31162)
CWE-ID: CWE-682 - Incorrect Calculation
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 a denial of service (DoS) attack.
The vulnerability exists due to a floating point exception within the get_slope() function. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Buffer overflow (CVE-ID: CVE-2025-31163)
CWE-ID: CWE-119 - Memory corruption
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 a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the put_patternarc() function. A remote attacker can pass specially crafted input to the application, trigger memory corruption and crash the application.
6) Heap-based buffer overflow (CVE-ID: CVE-2025-31164)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
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 a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the create_line_with_spline() function. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.
