In versions 1.0 through 2.0b4, cpdb-libs is vulnerable to buffer overflows via improper use of `scanf(3)`. cpdb-libs uses the `fscanf()` and `scanf()` functions to parse command lines and configuration files, dropping the read string components into fixed-length buffers, but does not limit the length of the strings to be read by `fscanf()` and `scanf()` causing buffer overflows when a string is longer than 1023 characters. A patch for this issue is available at commit f181bd1f14757c2ae0f17cc76dc20421a40f30b7. As all buffers have a length of 1024 characters, the patch limits the maximum string length to be read to 1023 by replacing all occurrences of `%s` with `%1023s` in all calls of the `fscanf()` and `scanf()` functions."}], "lastModified": "2025-04-10T20:35:56.547", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openprinting:cpdb-libs:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "57F84EB4-6BF2-4AAA-9BC6-F881F046A97B", "versionEndExcluding": "2.0", "versionStartIncluding": "1.0"}, {"criteria": "cpe:2.3:a:openprinting:cpdb-libs:2.0:beta1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "367C92BD-4CA9-4024-B9FA-7430236C9F6F"}, {"criteria": "cpe:2.3:a:openprinting:cpdb-libs:2.0:beta2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CED72D06-A6D2-486F-B3FA-6ADA82262C6B"}, {"criteria": "cpe:2.3:a:openprinting:cpdb-libs:2.0:beta3:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8545935C-24E9-49F6-8EBE-4D49F2C72F81"}, {"criteria": "cpe:2.3:a:openprinting:cpdb-libs:2.0:beta4:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F7330E46-2ACD-4832-89F9-D0372C9BFF06"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
