Security update for jq
Multiple vulnerabilities in jq can cause process crashes due to unbounded or uncontrolled recursion, heap out-of-bounds writes, and buffer overruns on 32-bit systems. These issues include stack exhaustion from recursive object merges and module loading, a heap corruption bug triggered by --rawfile with oversized strings, and an integer overflow leading to buffer overrun.
AI Analysis
Technical Summary
This security update for jq addresses four vulnerabilities: CVE-2026-43896 involves unbounded recursion in jv_object_merge_recursive() causing C stack exhaustion and process crash; CVE-2026-44777 involves uncontrolled recursion in the module loader when two valid modules include each other, also causing stack exhaustion and crash; CVE-2026-49839 fixes a bug where jq --rawfile can convert a handled oversized-string error into a heap out-of-bounds write in assertion-disabled builds; CVE-2026-54679 addresses an integer overflow in jvp_string_append that can cause a buffer overrun on 32-bit systems. These vulnerabilities can lead to denial of service or memory corruption.
Potential Impact
Exploitation of these vulnerabilities can cause jq processes to crash due to stack exhaustion or trigger memory corruption through heap out-of-bounds writes and buffer overruns. This can result in denial of service or potentially undefined behavior in affected environments. There is no indication of active exploitation in the wild.
Mitigation Recommendations
A security update is available that fixes these vulnerabilities. Users should apply the update to the affected jq version =1.7.1-160000.4.1.aarch64 as provided by the SUSE Product Security Team. No additional mitigation steps are indicated.
