When parsing `multi-bulk` (array-like) replies, hiredis fails to check if `count * sizeof(redisReply*)` can be represented in `SIZE_MAX`. If it can not, and the `calloc()` call doesn't itself make this check, it would result in a short allocation and subsequent buffer overflow.</p> + </description> + <impact type="normal"> + <p>Malicious Redis commands could result in remote code execution.</p> + </impact> + <workaround> + <p>There is no known workaround at this time.</p> + </workaround> + <resolution> + <p>All hiredis users should upgrade to the latest version:</p> + + <code> + # emerge --sync + # emerge --ask --oneshot --verbose ">=dev-libs/hiredis-1.0.1" + </code> + + <p>All hiredis-py users should upgrade to the latest version:</p> + + <code> + # emerge --sync + # emerge --ask --oneshot --verbose ">=dev-python/hiredis-2.0.0" + </code> + </resolution> + <references> + <uri link="https://nvd.nist.gov/vuln/detail/CVE-2021-32765">CVE-2021-32765</uri> + </references> + <metadata tag="requester" timestamp="2022-10-31T01:29:20.506011Z">ajak</metadata> + <metadata tag="submitter" timestamp="2022-10-31T01:29:20.514033Z">ajak</metadata> +</glsa>
