Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2023-38802)

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

The vulnerability exists due to insufficient validation of user-supplied input when processing BGP update data with a corrupted attribute 23 (Tunnel Encapsulation). A remote attacker can send specially crafted BGP update data to the application and perform a denial of service (DoS) attack.


2) Input validation error (CVE-ID: CVE-2023-41358)

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

The vulnerability exists due to insufficient validation of user-supplied input in bgpd/bgp_packet.c when handling NLRIs. A remote attacker can send specially crafted input to the application and perform a denial of service (DoS) attack.


3) NULL pointer dereference (CVE-ID: CVE-2023-41909)

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

The vulnerability exists due to a NULL pointer dereference error within the bgp_nlri_parse_flowspec() function in bgpd/bgp_flowspec.c. A remote attacker can send specially crafted data to the application and perform a denial of service (DoS) attack.


4) Out-of-bounds read (CVE-ID: CVE-2023-41360)

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

The vulnerability exists due to a boundary condition in bgpd/bgp_packet.c. A remote attacker can read the initial byte of the ORF header in an ahead-of-stream situation.


5) Out-of-bounds read (CVE-ID: CVE-2023-41359)

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

The vulnerability exists due to a boundary condition within the bgp_attr_aigp_valid() function in bgpd/bgp_attr.c. A remote attacker can send specially crafted data to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.


6) Buffer overflow (CVE-ID: CVE-2023-41361)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in bgpd/bgp_open.c. A remote attacker can send specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.
