Description

jq is a command-line JSON processor. Prior to 1.8.2, on 32bit system, jvp_string_append has a chance of integer/multiple overflowing and then causing a massive buffer overrun. This vulnerability is fixed in 1.8.2.

Summary dbcve.org

jq versions prior to 1.8.2 contain an integer/multiple overflow vulnerability in the jvp_string_append function on 32-bit systems, which can lead to a buffer overrun. This flaw exists specifically in how the function handles string length calculations on 32-bit architectures.

Mitigation

Upgrade jq to version 1.8.2 or later to patch the integer overflow vulnerability in jvp_string_append; on 32-bit systems, ensure the patched version is deployed.
