Description

This security bulletin contains information about 4 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2020-6628)

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 a boundary condition in the "decompile_SWITCH()" function in decompile.c. A remote attacker can trigger out-of-bounds read error and cause a denial of service condition on the target system.


2) NULL pointer dereference (CVE-ID: CVE-2020-6629)

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 the "decompileGETURL2()" function in "decompile.c" file. A remote attacker can perform a denial of service (DoS) attack.


3) Out-of-bounds read (CVE-ID: CVE-2020-11894)

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 (8 bytes) in the "decompileIF()" function in "decompile.c" file. A remote attacker can perform a denial of service attack.


4) Out-of-bounds read (CVE-ID: CVE-2020-11895)

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 (2 bytes) in the "decompileIF()" function in "decompile.c" file. A remote attacker can perform a denial of service attack.
