Description
This security bulletin contains information about 2 vulnerabilities.
1) Memory leak (CVE-ID: CVE-2026-32874)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to missing release of memory after effective lifetime in the JSON parser when parsing large integer values in untrusted JSON input. A remote attacker can send a specially crafted JSON payload containing large integers to cause a denial of service.
The issue is triggered for integers outside the range [-2^63, 2^64 - 1], and the leak occurs even if parsing fails because the integer exceeds sys.get_int_max_str_digits().
2) Integer overflow (CVE-ID: CVE-2026-32875)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to integer overflow or underflow in ujson.dumps() indentation handling when processing user-controlled indent values during JSON serialization of nested input. A remote attacker can supply a specially crafted indent value to cause a denial of service.
The issue can result in a segmentation fault when the indent value and nesting depth exceed INT32_MAX, or an infinite loop when a large negative indent is used.
