SB20260819113 - openEuler 24.03 LTS SP3 update for jq

Description

This security bulletin contains information about 3 vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2026-47770)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to stack-based buffer overflow in deep structural equality when parsing input. A local user can supply specially crafted input to cause a denial of service.

2) Out-of-bounds write (CVE-ID: CVE-2026-49839)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to out-of-bounds write in the --rawfile handling in jv_load_file() when processing an attacker-controlled file. A remote attacker can supply a crafted oversized file to cause a denial of service.

User interaction is required to process the crafted file, and the heap-buffer-overflow occurs in assertion-disabled builds after a handled \"String too long\" error is reused as a string state.

3) Integer overflow (CVE-ID: CVE-2026-54679)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to cause a denial of service or execute arbitrary code.

The vulnerability exists due to integer overflow leading to a heap-based buffer overflow in jvp_string_append when appending data to strings on 32-bit systems. A local user can supply crafted input that triggers oversized string growth calculations to cause a denial of service or execute arbitrary code.

Only 32-bit systems are affected.

Remediation
