CVE-2026-55211: CWE-125: Out-of-bounds Read in equinor surfio
Surfio is a library for reading and writing surface files. Prior to 0.0.19, surfio does not correctly validate size fields in IRAP files, leading to a buffer overflow when untrusted files are parsed. The severity assumes surfio is used to parse untrusted files in a networking context such as a web service. This issue is fixed in version 0.0.19.
AI Analysis
Technical Summary
The equinor surfio library, used for reading and writing surface files, contains an out-of-bounds read vulnerability (CWE-125) in versions prior to 0.0.19. This occurs due to incorrect validation of size fields in IRAP files, potentially causing a buffer overflow during parsing of untrusted files. The vulnerability has a CVSS 3.0 score of 9.8, indicating critical severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The flaw is fixed in surfio version 0.0.19.
Potential Impact
Successful exploitation can lead to a buffer overflow, resulting in high impact on confidentiality, integrity, and availability. This could allow remote attackers to execute arbitrary code or cause denial of service when surfio parses malicious IRAP files in network-exposed services.
Mitigation Recommendations
Upgrade surfio to version 0.0.19 or later, where this vulnerability is fixed. No other mitigation is indicated.
