CVE-2026-49838

A flaw was found in GoBGP, an open-source Border Gateway Protocol BGP implementation. A configured confederation eBGP peer can send a specially crafted BGP UPDATE message with a zero-length ASPATH attribute. This malformed message is improperly handled during validation, leading to an unchecked...

CVE-2026-49838

GoBGP is an open source Border Gateway Protocol BGP implementation in the Go Programming Language. Prior to version 4.7.0, GoBGP accepts a zero-length ASPATH during UPDATE decoding and later panics while validating that attribute for a confederation eBGP peer. The vulnerable path is in the BGP...

CVE-2026-49838

GoBGP , an open-source BGP implementation in Go, is vulnerable to a denial-of-service in its BGP UPDATE validator prior to version 4.7.0 . When a confederation eBGP peer sends a malformed UPDATE containing a zero-length AS_PATH , the attribute passes initial decoding but triggers an unchecked p.V...

GoBGP is an open source Border Gateway Protocol BGP implementation in the Go Programming Language. Prior to version 4.7.0, GoBGP accepts a zero-length ASPATH during UPDATE decoding and later panics while validating that attribute for a confederation eBGP peer. The vulnerable path is in the BGP...

CVE-2026-49838 GoBGP confederation validation panics on empty AS_PATH attribute

GoBGP is an open source Border Gateway Protocol BGP implementation in the Go Programming Language. Prior to version 4.7.0, GoBGP accepts a zero-length ASPATH during UPDATE decoding and later panics while validating that attribute for a confederation eBGP peer. The vulnerable path is in the BGP...

Improper Validation of Array Index

Overview Affected versions of this package are vulnerable to Improper Validation of Array Index in the validation process for BGP UPDATE messages containing an empty ASPATH attribute. An attacker can cause a panic and terminate the peer session by sending a malformed UPDATE with a zero-length...

USN-8429-1 fastnetmon vulnerabilities

It was discovered that FastNetMon incorrectly validated prefix lengths when decoding BGP NLRI data. A remote attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 26.04 LTS. CVE-2026-48686 It was...

CVE-2026-48691

FastNetMon Community Edition through 1.2.9 contains an integer overflow in the BGP ASPATH attribute encoder. In src/bgpprotocol.hpp, the IPv4UnicastAnnounce::getattributes function computes attributelength as 'sizeofbgpaspathsegmentelementt + this-aspathasns.size sizeofuint32t' and stores it in a...

Quagga aspath_put BGP Session Drop Denial of Service (CVE-2017-16227)

A denial-of-service vulnerability exists in Quagga. The vulnerability is due to an improper calculation of ASPATH. A remote attacker can exploit this vulnerability by sending a specially crafted request to the affected service. Successful exploitation would cause the target to crash, resulting in...

SUSE SLES11 Security Update : quagga (SUSE-SU-2018:0457-1)

This update for quagga fixes the following issues : - The Quagga BGP daemon contained a bug in the ASPATH size calculation that could have been exploited to facilitate a remote denial-of-service attack via specially crafted BGP UPDATE messages. CVE-2017-16227, bsc1065641 - The Quagga BGP daemon d...

Design/Logic Flaw

The aspathput function in bgpd/bgpaspath.c in Quagga before 1.2.2 allows remote attackers to cause a denial of service session drop via BGP UPDATE messages, because ASPATH size calculation for long paths counts certain bytes twice and consequently constructs an invalid message...
