This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables. The default behavior when the stack-protector detects an overflow is to terminate your application, resulting in controlled loss of availability. An attacker who can exploit a buffer overflow without triggering the stack-protector might be able to change program flow control to cause an uncontrolled loss of availability or to go further and affect confidentiality or integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by itself.", "references": [ { "reference_url": "https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2023-4039.json", "reference_id": "", "reference_type": "", "scores": [], "url": "https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2023-4039.json" }, { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2023-4039", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.00185", "scoring_system": "epss", "scoring_elements": "0.40119", "published_at": "2026-06-05T12:55:00Z" }, { "value": "0.00185", "scoring_system": "epss", "scoring_elements": "0.40121", "published_at": "2026-06-06T12:55:00Z" }, { "value": "0.00185", "scoring_system": "epss", "scoring_elements": "0.40093", "published_at": "2026-06-07T12:55:00Z" }, { "value": "0.00185", "scoring_system": "epss", "scoring_elements": "0.40065", "published_at": "2026-06-08T12:55:00Z" }, { "value": "0.00185", "scoring_system": "epss", "scoring_elements": "0.40082", "published_at": "2026-06-09T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2023-4039" }, { "reference_url": "https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-4039", "reference_id": "", "reference_type": "", "scores": [], "url": "https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-4039" }, { "reference_url": "https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.8", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N" } ], "url": "https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml" }, { "reference_url": "https://bugzilla.redhat.com/show_bug.cgi?id=2233236", "reference_id": "2233236", "reference_type": "", "scores": [], "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2233236" }, { "reference_url": "https://usn.ubuntu.com/7700-1/", "reference_id": "USN-7700-1", "reference_type": "", "scores": [], "url": "https://usn.ubuntu.com/7700-1/" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/96014?format=api", "purl": "pkg:deb/debian/gcc-11@11.4.0-4?distro=sid", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:deb/debian/gcc-11@11.4.0-4%3Fdistro=sid" }, { "url": "http://public2.vulnerablecode.io/api/packages/96012?format=api", "purl": "pkg:deb/debian/gcc-11@11.5.0-11?distro=sid", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:deb/debian/gcc-11@11.5.0-11%3Fdistro=sid" } ], "aliases": [ "CVE-2023-4039" ], "risk_score": 1.2, "exploitability": "0.5", "weighted_severity": "2.4", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-y8uz-r8z9-nubj" } ], "fixing_vulnerabilities": [], "risk_score": "1.2", "resource_url": "http://public2.vulnerablecode.io/packages/pkg:deb/debian/gcc-11@11.3.0-12%3Fdistro=sid" }
