CyberRota Analysis
AI-GeneratedThe mtr tool is susceptible to an out-of-bounds read vulnerability in the ipinfo_lookup() function, which can be exploited by an attacker who manipulates the DNS response for AS lookups. By returning a DNS response larger than 512 bytes with a crafted compression pointer, the attacker can cause a crash of the mtr application. Users of mtr versions up to 0.96 should prioritize applying the fix from commit 48e1794414d338ce47abc0f27c25ade8788af9c3 to mitigate this risk.

Original NVD Description
mtr is vulnerable to Out-of-bound read vulnerability in ipinfo_lookup() function. An attacker who can influence the TXT response used for AS lookups can trigger this bug by returning a DNS response that is larger than 512 bytes and uses a crafted compression pointer in the answer NAME field. ipinfo_lookup() function uses the length of the response as the end-of-message boundary for dn_expand() function. The result is a reliable crash. This issue exists in the mtr through version 0.96 and it was fixed in commit 48e1794414d338ce47abc0f27c25ade8788af9c3.
