Continued receipt and processing of these malformed BGP update messages will create a sustained Denial of Service (DoS) condition.\n\nUpon receipt of a BGP update message over an established BGP session containing a specifically malformed tunnel encapsulation attribute, when segment routing is enabled, internal processing of the malformed attributes within the update results in improper parsing of remaining attributes, leading to session reset:\n\nBGP SEND Notification code 3 (Update Message Error) subcode 1 (invalid attribute list)\n\nOnly systems with segment routing enabled are vulnerable to this issue.\n\nThis issue affects eBGP and iBGP, in both IPv4 and IPv6 implementations, and requires a remote attacker to have at least one established BGP session.\n\nThis issue affects:\n\nJunos OS: \n\n\n  *  All versions before 21.4R3-S8, \n  *  from 22.2 before 22.2R3-S4, \n  *  from 22.3 before 22.3R3-S3, \n  *  from 22.4 before 22.4R3-S3, \n  *  from 23.2 before 23.2R2-S1, \n  *  from 23.4 before 23.4R1-S2, 23.4R2.\n\n\nJunos OS Evolved:\u00a0\n\n  *  All versions before 21.4R3-S8-EVO, \n  *  from 22.2-EVO before 22.2R3-S4-EVO, \n  *  from 22.3-EVO before 22.3R3-S3-EVO, \n  *  from 22.4-EVO before 22.4R3-S3-EVO, \n  *  from 23.2-EVO before 23.2R2-S1-EVO, \n  *  from 23.4-EVO before 23.4R1-S2-EVO, 23.4R2-EVO.\n\ud83d\udccf Published: 2024-07-11T00:32:51Z\n\ud83d\udccf Modified: 2025-02-07T21:30:58Z\n\ud83d\udd17 References:\n1. https://nvd.nist.gov/vuln/detail/CVE-2024-39555\n2. https://supportportal.juniper.net/JSA83015", "creation_timestamp": "2025-02-07T22:03:09.000000Z"}
