Description

This security bulletin contains information about 3 vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2019-8907)

CWE-ID: CWE-121 - Stack-based buffer overflow

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


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to stack-based buffer overflow in the do_core_note function. A remote attacker can trick the victim into executing a file that submits malicious input to the targeted system with the file command, trigger memory corruption and perform a denial of service attack.


2) Stack out-of-bounds read (CVE-ID: CVE-2019-8905)

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

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


The vulnerability allows a remote attacker to obtain potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to stack-based buffer over-read in the do_core_note function, related to file_printable. A remote attacker can trick the victim into executing a file that submits malicious input to the targeted system with the file command, trigger memory corruption and gain access to arbitrary data or perform a denial of service attack.
