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


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to an error when handling malicious input. A remote unauthenticated attacker can cause a remote server to return a specially crafted reply to cause the target X client to crash.


2) Off-by-one error (CVE-ID: CVE-2018-14599)

CWE-ID: CWE-193 - Off-by-one Error

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 execute arbitrary code on the target system.

The vulnerability exists due to an off-by-one memory write error in the XGetFontPath(), XListExtensions(), and XListFonts() functions. A remote unauthenticated attacker can cause a remote X server to return a specially crafted response to trigger memory corruption and execute arbitrary code on the target X client.

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


3) Out-of-bounds write (CVE-ID: CVE-2018-14600)

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

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 out-of-bounds write when handling malicious input. A remote unauthenticated attacker can trick the victim into opening a specially crafted data, trigger memory corruption and execute arbitrary code on the target X client.

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