Altran picoTCP through 1.7.0 allows memory corruption and subsequent denial of service because of an integer overflow in picoipv6alloc when processing large ICMPv6 packets. This affects installations with Ethernet support in which a packet size greater than 65495 may occur...

picoTCP 输入验证错误漏洞

Altran picoTCP is a small footprint modular open source TCP/IP stack from Altran, France, designed for embedded systems and the Internet of Things. A security vulnerability exists in picoTCP 1.7.0 and earlier versions, which stems from the presence of an integer overflow that can be exploited by ...

CVE-2023-30463

CVE-2023-30463 affects Altran picoTCP up to 1.7.0. The root cause is an integer overflow in pico_ipv6_alloc when processing large ICMPv6 packets, leading to memory corruption and denial of service in Ethernet-enabled deployments where packet size exceeds 65495. The provided documents do not speci...

SUSE 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...

SUSE 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...

SUSE 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...

SUSE CVE-2020-24337

An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. When an unsupported TCP option with zero length is provided in an incoming TCP packet, it is possible to cause a Denial-of-Service by achieving an infinite loop in the code that parses TCP options, aka tcpparseoptions in picotcp.c...

SUSE CVE-2020-24340

An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The code that processes DNS responses in picomdnshandledataasanswersgeneric in picomdns.c does not check whether the number of answers/responses specified in a DNS packet header corresponds to the response data available in the...
