CVE-2019-3823
CVSS v2.0
7.5
High
| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
libcurl versions 7.34.0 through 7.64.0
Description
The issue is related to a heap out-of-bounds read in the code handling the end-of-response for SMTP. This occurs when the buffer passed to
smtp endofresp() is not null terminated and contains no character ending the parsed number, and len is set to 5. As a result, the strtol() call reads beyond the allocated buffer, but the read contents are not returned to the caller. The exploitation of this issue may allow a remote attacker to impact the confidentiality, integrity, and availability of protected information, potentially leading to a denial of service.Recommendations
For libcurl versions 7.34.0 through 7.64.0, update to a version that contains a fix for this issue.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
