An issue in the parse_month function (/time/strptime.rs) of relibc commit ab6a2e allows attackers to cause a Denial of Service (DoS) via parsing a crafted input.
AI Analysis
Technical Summary
The vulnerability exists in the parse_month function within the /time/strptime.rs source file of relibc (commit ab6a2e). An attacker can exploit this flaw by supplying specially crafted input to the function, causing a Denial of Service condition. The CVSS v3.1 base score is 7.5, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to availability (DoS). There is no information about any available patch or vendor advisory at this time.
Potential Impact
Successful exploitation results in a Denial of Service (DoS) condition, impacting the availability of applications or systems using the vulnerable parse_month function in relibc. There is no confidentiality or integrity impact reported. No known exploits are currently observed in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should consider mitigating exposure by restricting access to services using the vulnerable code or applying input validation to prevent malformed inputs from reaching the parse_month function.
