jq: Buffer overflow

jq: Buffer overflow A buffer overflow in jq might allow remote attackers to execute arbitrary code. jq 2016-12-08 2016-12-08 580606 remote 1.5-r2 1.5-r2

jq is a lightweight and flexible command-line JSON processor.

An off-by-one error was discovered in the tokenadd function in jv_parse.c which triggers a heap-based buffer overflow.

A remote attacker could trick a victim into processing a specially crafted JSON file, possibly resulting in the execution of arbitrary code with the privileges of the process. Additionally, a remote attacker could cause a Denial of Service condition.

There is no known workaround at this time.

All jq users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=app-misc/jq-1.5-r2"
