CVE-2019-5435

CVSS v2.0

4.3

Medium

VectorAV:N/AC:M/Au:N/C:N/I:N/A:P
Name of the Vulnerable Software and Affected Versions libcurl versions 7.62.0 through 7.64.1
Description The issue is related to an integer overflow in the curl url set() function of the libcurl library. This overflow can lead to a buffer overflow, potentially allowing a remote attacker to cause a denial of service or impact the availability of protected information. The flaws are specific to 32-bit architectures and require excessive string input lengths to be triggered.
Recommendations For libcurl versions 7.62.0 through 7.64.1, consider updating to a version that fixes the integer overflow issue in the curl url set() function to prevent potential buffer overflows. As a temporary workaround, consider restricting input lengths to the curl url set() function to minimize the risk of exploitation.
