It is not written in memory-safe langauges (C and C++11),\nresulting in several CVEs over the years (e.g. CVE-2021-34813 and\nCVE-2021-44538). It also depends on simplistic cryptography primitive\nimplementations which are intended for pragmatic and education purposes rather\nthan security - e.g. Brad Conte's crypto-algorithms.\n\nAs a result, the libolm team rewrote libolm in Rust in December 2021 - the\nresult being vodozemac, and announced it as the recommended successor to libolm\nafter its audit by Least Authority in May 2022.\n","package_architecture":"amd64","stem":"olm","readme":null,"dependencies":[{"path":"devel/cmake/core","type":"build","package_spec":"STEM->=4","url":"/packages/release/devel/cmake/core/"},{"path":"devel/ninja","type":"build","package_spec":"","url":"/packages/release/devel/ninja/"}],"reverse_dependencies":{"count":9,"url":"/packages/data/32/329b95981ad9d501c9847a3a20f1d4ba8086477ba1b53e27dcc0535cafb9a614.json"},"categories":["devel","security"],"flavors":[],"only_for_architectures":["aarch64","amd64","arm","i386","mips64","mips64el","powerpc","powerpc64","riscv64","alpha","hppa","sparc64"],"not_for_architectures":[]}}
