CVE-2024-6197 (opens in a new tab)How to fix?
Upgrade curl to version 8.9.0 or higher.
Overview
curl is a command line tool and library for transferring data with URL syntax, supporting DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET and TFTP. libcurl offers a myriad of powerful features.
Affected versions of this package are vulnerable to Free of Memory not on the Heap in the ASN1 parser, through the utf8asn1str function, upon detecting an invalid ASN.1 UTF-8 string, erroneously invokes free() on a 4-byte local stack buffer. This can lead to the overwriting of nearby stack memory, potentially causing a crash or, in special circumstances, more severe outcomes.
Exploiting this vulnerability is possible on a system that uses a malloc implementation that does not immediately abort upon error.
