Alert meAnalysisAI
In the Opaque LSA Extended Link parser in FRRouting (FRR) through 9.1, there can be a buffer overflow and daemon crash in ospf_te_parse_ext_link for OSPF LSA packets during an attempt to read Segment. Rated medium severity (CVSS 6.5), this vulnerability is no authentication required, low attack complexity. This Buffer Copy without Size Check vulnerability could allow attackers to overflow a buffer to corrupt adjacent memory.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.

Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
