Description

This security bulletin contains information about 5 vulnerabilities.


1) Type conversion (CVE-ID: N/A)

CWE-ID: CWE-704 - Type conversion

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:P/U:Green


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

The vulnerability exists due to a type confusion in the "tcpedit_dlt_getplugin". A remote attacker can cause a denial of service condition on the target system.


2) Out-of-bounds write (CVE-ID: N/A)

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

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


The vulnerability allows a local attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the tcp_opt fragroute module. A local attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.


3) Out-of-bounds write (CVE-ID: N/A)

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

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


The vulnerability allows a local attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the ip6_opt fragroute module. A local attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.


4) Out-of-bounds write (CVE-ID: N/A)

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

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


The vulnerability allows a local user to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in src/common/sendpacket.c within KHIAL interface. A local user can trigger an out-of-bounds write and gain access to senitive informatio on perform a denial of service (DoS) attack.


5) NULL pointer dereference (CVE-ID: N/A)

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:P/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 remove_settings function. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
