RSEC-2023-4

The igraph R package, through version 0.7.1, is susceptible to a vulnerability identified in the igraphistrdiff function within igraph_trie.c. This vulnerability can lead to a NULL pointer dereference, potentially exploited by attackers to cause a denial of service, resulting in an application crash. Users of the igraph package should take necessary precautions and consider updating to a patched version to mitigate this security risk.
