CVE-2024-35329

Publication date 11 June 2024

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

** DISPUTED ** libyaml 0.2.5 is vulnerable to a heap-based Buffer Overflow in yaml_document_add_sequence in api.c. NOTE: the supplier disputes this because the finding represents a user error. The problem is that the application, which was making use of the libyaml library, omitted the required calls to the yaml_document_initialize and yaml_document_delete functions.

golang-goyaml is a go translation of libyaml and shouldn't share implementation flaws, but may share design flaws
