Description

This security bulletin contains information about 4 vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2022-27404)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the "sfnt_init_face" function. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.


2) Out-of-bounds read (CVE-ID: CVE-2022-27405)

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 "FNT_Size_Request" function. A remote attacker can trigger out-of-bounds read error and cause a denial of service condition on the system.


3) Out-of-bounds read (CVE-ID: CVE-2022-27406)

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 "FT_Request_Size" function. A remote attacker can trigger out-of-bounds read error and cause a denial of service condition on the system.


4) Integer overflow (CVE-ID: CVE-2023-2004)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/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 integer overflow within the tt_hvadvance_adjust() function in src/truetype/ttgxvar.c. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
