CVE-2021-31226

CVE-2021-31226 affects HCC Embedded InterNiche/NicheStack (4.0.1) and is caused by a lack of input size validation in the HTTP POST parser, leading to a heap buffer overflow in wbs_post() via strcpy() when a crafted URI longer than 50 bytes is sent. Red Hat/RedHat CVE entries corroborate a heap o...

CVE-2020-25767

An issue was discovered in HCC Embedded NicheStack IPv4 4.1. The dnccopyin routine for parsing DNS domain names does not check whether a domain name compression pointer is pointing within the bounds of the packet e.g., forward compression pointer jumps are allowed, which leads to an Out-of-bounds...

CVE-2020-25767

CVE-2020-25767 affects HCC Embedded InterNiche/NicheStack (IPv4) prior to 4.3. The root cause is in the dnc_copy_in DNS domain name parser, which fails to validate that compression pointers stay within packet bounds, enabling an out-of-bounds read and potential DoS via crafted DNS data. Affected ...
