Description

This security bulletin contains information about 5 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2019-1343)

CWE-ID: CWE-119 - Memory corruption

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


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

The vulnerability exists due to a boundary error when processing certain files. A remote attacker can trick a victim to open a specially crafted file from a remote location, trigger memory corruption and cause the system to stop responding.

Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.


2) Buffer overflow (CVE-ID: CVE-2019-1346)

CWE-ID: CWE-119 - Memory corruption

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


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

The vulnerability exists due to a boundary error when processing certain files. A remote attacker can trick a victim to open a specially crafted file from a remote location, trigger memory corruption and cause the system to stop responding.

Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.


3) Buffer overflow (CVE-ID: CVE-2019-1347)

CWE-ID: CWE-119 - Memory corruption

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


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

The vulnerability exists due to a boundary error when processing certain files. A remote attacker can trick a victim to open a specially crafted file from a remote location, trigger memory corruption and cause the system to stop responding.

Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.


4) Input validation error (CVE-ID: CVE-2019-1325)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to the way the Windows redirected drive buffering system (rdbss.sys) handles local calls within Windows 7 for 32-bit systems. A local user can run a specially crafted application that send a specific local call and perform a denial of service (DoS) attack.


5) Windows Hard Link (CVE-ID: CVE-2019-1317)

CWE-ID: CWE-65 - Windows hard link

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


The vulnerability allows a local user to cause a denial of service (DoS) condition on the target  system.

The vulnerability exists due to Windows improperly handles hard links. A local authenticated user can run a specially crafted application and cause a target system to stop responding. This vulnerability would allow an attacker to overwrite system files.
