In the second pass, when emitting UTF-8 bytes,\nthe helper function bmp_to_utf8() incorrectly forwards the remaining UTF-16\nsource byte count as the destination buffer capacity to UTF8_putc(). For BMP\ncode points above U+07FF, UTF-8 requires three bytes, but the forwarded\ncapacity can be just two bytes. UTF8_putc() then returns -1, and this negative\nvalue is added to the output length without validation, causing the\nlength to become negative. The subsequent trailing NUL byte is then written\nat a negative offset, causing write outside of heap allocated buffer.\nThe vulnerability is reachable via the public PKCS12_get_friendlyname() API\nwhen parsing attacker-controlled PKCS#12 files. While PKCS12_parse() uses a\ndifferent code path that avoids this issue, PKCS12_get_friendlyname() directly\ninvokes the vulnerable function. Exploitation requires an attacker to provide\na malicious PKCS#12 file to be parsed by the application and the attacker\ncan just trigger a one zero byte write before the allocated buffer.\nFor that reason the issue was assessed as Low severity according to our\nSecurity Policy.\nThe FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,\nas the PKCS#12 implementation is outside the OpenSSL FIPS module boundary.\nOpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this issue.\nOpenSSL 1.0.2 is not affected by this issue.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "fixed": [ "AlmaLinux-9.2:compat-openssl11-1:1.1.1k-4.el9_0.tuxcare.els2.i686", "AlmaLinux-9.2:compat-openssl11-1:1.1.1k-4.el9_0.tuxcare.els2.x86_64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2025-69419" } ], "release_date": "2026-01-27T00:00:00Z", "remediations": [ { "category": "vendor_fix", "date": "2026-03-16T13:50:08.118606Z", "details": "Details on how to apply the fix are available at: https://cve.tuxcare.com/els/releases/CLSA-2026:1773669005", "product_ids": [ "AlmaLinux-9.2:compat-openssl11-1:1.1.1k-4.el9_0.tuxcare.els2.i686", "AlmaLinux-9.2:compat-openssl11-1:1.1.1k-4.el9_0.tuxcare.els2.x86_64" ], "url": "https://cve.tuxcare.com/els/releases/CLSA-2026:1773669005" } ], "scores": [ { "cvss_v3": { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 7.4, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N", "version": "3.1" }, "products": [ "AlmaLinux-9.2:compat-openssl11-1:1.1.1k-4.el9_0.tuxcare.els2.i686", "AlmaLinux-9.2:compat-openssl11-1:1.1.1k-4.el9_0.tuxcare.els2.x86_64" ] } ], "threats": [ { "category": "impact", "details": "Important" } ] } ] }
