24
FAUCET Score

CVE-2021-42523 describes two information disclosure vulnerabilities within the colord_project colord software, specifically in cd-device-db.c and cd-profile-db.c. These flaws stem from the failure to release the 'err_msg' buffer after sqlite3_exec calls, leading to potential exposure of sensitive data. With a CVSS score of 7.5 (High), this vulnerability is remotely exploitable with low complexity, allowing an unauthenticated attacker to achieve high confidentiality impact. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.

colord: potential memory leak, forgetting to free error message of libsqlite3 API 'sqlite3_exec' -1

Oct 6, 2022
microsoft2022-Aug/CVE-2021-42523Important

There are two Information Disclosure vulnerabilities in colord and they lie in colord/src/cd-device-db.c and colord/src/cd-profile-db.c separately. They exist because the 'err_msg' of 'sqlite3_exec' is not releasing after use while libxml2 emphasizes that the caller needs to release it.
