CVE-2020-17469

Concrete details available: CVE-2020-17469 affects FNET up to version 4.6.4 in the IPv6 fragment reassembly path. The bug is an uninitialized pointer dereference in _fnet_ip6_reassembly (fnet_ip6.c) when handling fragments with holes in a non-empty list, enabling Denial-of-Service. Affects FNET's...

CVE-2020-17469

An issue was discovered in FNET through 4.6.4. The code for IPv6 fragment reassembly tries to access a previous fragment starting from a network incoming fragment that still doesn't have a reference to the previous one which supposedly resides in the reassembly list. When faced with an incoming...

CVE-2020-17468

CVE-2020-17468 – FNET : A flaw in FNET up to v4.6.4 in the IPv6 hop-by-hop extension header processing does not validate the extension header length, enabling an out-of-bounds read that can cause Denial-of-Service. Connected sources corroborate the issue as part of AMNESIA:33, affecting FNET’s fn...

CVE-2020-17468

An issue was discovered in FNET through 4.6.4. The code for processing the hop-by-hop header in the IPv6 extension headers doesn't check for a valid length of an extension header, and therefore an out-of-bounds read can occur in fnetip6extheaderhandleroptions in fnetip6.c, leading to...

CVE-2020-17445

An issue was discovered in picoTCP 1.7.0. The code for processing the IPv6 destination options does not check for a valid length of the destination options header. This results in an Out-of-Bounds Read, and, depending on the memory protection mechanism, this may result in Denial-of-Service in...

CVE-2020-17444

CVE-2020-17444 affects picoTCP-NG and picoTCP 1.7.0, where the IPv6 extension header length field is not checked for overflow. If the header length wraps to zero, the extension-header parsing loop can stall, causing an infinite loop DoS in pico_ipv6_check_headers_sequence(). The SUSE/NVD entries ...

CVE-2020-17442

CVE-2020-17442 affects picoTCP (and picoTCP-NG) 1.7.0. The issue is in parsing IPv6 hop-by-hop extension headers, where the header length bound is not validated, enabling integer wraparound and a potential DoS in pico_ipv6_process_hopbyhop(). Public details are provided in the SUSE/FORESA advisor...

CVE-2020-17442

An issue was discovered in picoTCP 1.7.0. The code for parsing the hop-by-hop IPv6 extension headers does not validate the bounds of the extension header length value, which may result in Integer Wraparound. Therefore, a crafted extension header length value may cause Denial-of-Service because it...

CVE-2020-17441

An issue was discovered in picoTCP 1.7.0. The code for processing the IPv6 headers does not validate whether the IPv6 payload length field is equal to the actual size of the payload, which leads to an Out-of-Bounds read during the ICMPv6 checksum calculation, resulting in either Denial-of-Service...
