Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2026-32316)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in the "jvp_string_append" and "jvp_string_copy_replace_bad" functions. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
2) Uncontrolled Recursion (CVE-ID: CVE-2026-33947)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncontrolled recursion in the "jv_setpath()", "jv_getpath()" and "delpaths_sorted()" functions in src/jv_aux.c. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) NULL pointer dereference (CVE-ID: CVE-2026-39956)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to jq _strindices missing runtime type checks. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack or gain access to sensitive information.
4) Out-of-bounds read (CVE-ID: CVE-2026-39979)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a boundary condition in the "jv_parse_sized()" function. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
5) Inefficient Algorithmic Complexity (CVE-ID: CVE-2026-40164)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to inefficient algorithmic complexity within hardcoded MurmurHash3 seed. A remote attacker can cause a denial of service condition on the target system.
