Detail
| Two vulnerabilities were discovered in cURL, an URL transfer library. CVE-2018-16839 Harry Sintonen discovered that, on systems with a 32 bit size_t, an integer overflow would be triggered when a SASL user name longer than 2GB is used. This would in turn cause a very small buffer to be allocated instead of the intended very huge one, which would trigger a heap buffer overflow when the buffer is used. CVE-2018-16842 Brian Carpenter discovered that the logic in the curl tool to wrap error messages at 80 columns is flawed, leading to a read buffer overflow if a single word in the message is itself longer than 80 bytes. For the stable distribution (stretch), these problems have been fixed in version 7.52.1-5+deb9u8. We recommend that you upgrade your curl packages. For the detailed security status of curl please refer to its security tracker page at: https://security-tracker.debian.org/tracker/curl |
