  "title": "Integer underflow in VMime uuencoded MIME decoding",
  "summary": "VMime through 0.9.2 is affected when it processes malformed uuencoded MIME content. An attacker who can cause an application to handle a crafted email may crash the application or potentially run code.",
  "mitigation": "Do not rely on a specific upgrade target: the evidence does not identify a fixed version. Reduce exposure by blocking or quarantining uuencoded email content before VMime processes it, and update when a vendor-confirmed fixed release is available.",
