Description

This security bulletin contains information about 7 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2020-6609)

CWE-ID: CWE-125 - Out-of-bounds read

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 heap-based buffer over-read in "read_pages_map" in decode_r2007.c. A remote attacker can perform a denial of service attack.


2) Memory leak (CVE-ID: CVE-2020-6610)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

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 (DoS) attack on the target system.

The vulnerability exists due to memory leak in "read_sections_map" in decode_r2007.c. A remote attacker can perform denial of service attack.


3) NULL pointer dereference (CVE-ID: CVE-2020-6611)

CWE-ID: CWE-476 - NULL Pointer Dereference

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 NULL pointer dereference error in "get_next_owned_entity" in dwg.c. A remote attacker can perform a denial of service (DoS) attack.


4) Out-of-bounds read (CVE-ID: CVE-2020-6612)

CWE-ID: CWE-125 - Out-of-bounds read

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
