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-2020-17441

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...

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-2020-17469

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

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-2020-17444

An issue was discovered in picoTCP 1.7.0. The routine for processing the next header field and deducing whether the IPv6 extension headers are valid doesn't check whether the header extension length field would overflow. Therefore, if it wraps around to zero, iterating through the extension heade...
