CVE-2019-18936:
Linux Debian vulnerability analysis and mitigation
Overview
CVE-2019-18936 affects UniValue library versions before 1.0.5. The vulnerability was discovered in the UniValue::read() function, which could allow attackers to cause a denial of service condition where the class internal data reaches an inconsistent state (NVD).
Technical details
The vulnerability exists in the UniValue::read() function where parsing edge cases could leave the class internal data in an inconsistent state when encountering input data errors. This was addressed by clearing the internal state upon error conditions (GitHub PR).
Impact
When exploited, the vulnerability allows attackers to cause a denial of service condition by manipulating the UniValue object into an inconsistent state through malformed input data (NVD).
Mitigation and workarounds
The vulnerability was fixed in UniValue version 1.0.5. Users should upgrade to this version or later to prevent potential denial of service attacks. The fix ensures that the internal state is properly cleared when parsing errors occur (GitHub PR).
