Detailsinfo

A vulnerability, which was classified as critical, was found in adns up to 1.5.1. Affected is some unknown functionality. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on availability. CVE summarizes:

An issue was discovered in adns before 1.5.2. adnshost mishandles a missing final newline on a stdin read. It is wrong to increment used as well as setting r, since used is incremented according to r, later. Rather one should be doing what read() would have done. Without this fix, adnshost may read and process one byte beyond the buffer, perhaps crashing or perhaps somehow leaking the value of that byte.

The weakness was disclosed 04/21/2023. The advisory is available at chiark.greenend.org.uk. This vulnerability is traded as CVE-2017-9108 since 05/21/2017. The technical details are unknown and an exploit is not available.

Upgrading to version 1.5.2 eliminates this vulnerability.
