| 标题 | osrg GoBGP 4.3.0 Off-by-one Error |
|---|
| 描述 | An off-by-one vulnerability was found in osrg GoBGP version 4.3.0. This vulnerability affects the CapSoftwareVersion.DecodeFromBytes function in the pkg/packet/bgp/bgp.go file. The root cause is an incorrect slice boundary calculation when extracting the Software Version string from a BGP OPEN capability payload. Because the Go slice upper bound is improperly calculated (using data[1:c.SoftwareVersionLen] instead of the correct data[1:1+c.SoftwareVersionLen]), the parser reads one byte fewer than intended. This causes the decoded Software Version string to be truncated, resulting in an inconsistency with the original encoded representation. |
