libcurl.so is vulnerable to a Stack-based Buffer Overflow. The vulnerability is due to improper handling of memory in the utf8asn1str
function, which invokes free
function on a 4-byte local stack buffer when detecting an invalid field. Attackers can exploit this flaw to overwrite nearby stack memory, potentially leading to DoS.
