Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-61abba57d8 advisory.

 - FRRouting FRR 7.5.1 through 9.0 and Pica8 PICOS 4.3.3.2 allow a remote attacker to cause a denial of service via a crafted BGP update with a corrupted attribute 23 (Tunnel Encapsulation). (CVE-2023-38802)

 - An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c processes NLRIs if the attribute length is zero. (CVE-2023-41358)

 - An issue was discovered in FRRouting FRR through 9.0. There is an out-of-bounds read in bgp_attr_aigp_valid in bgpd/bgp_attr.c because there is no check for the availability of two bytes during AIGP validation. (CVE-2023-41359)

 - An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c can read the initial byte of the ORF header in an ahead-of-stream situation. (CVE-2023-41360)

 - An issue was discovered in FRRouting FRR through 9.0. bgp_nlri_parse_flowspec in bgpd/bgp_flowspec.c processes malformed requests with no attributes, leading to a NULL pointer dereference. (CVE-2023-41909)

 - An issue found in Frrouting bgpd v.8.4.2 allows a remote attacker to cause a denial of service via the bgp_capability_llgr() function. (CVE-2023-31489)

 - An issue found in Frrouting bgpd v.8.4.2 allows a remote attacker to cause a denial of service via the bgp_attr_psid_sub() function. (CVE-2023-31490)
