CVE-2017-1000100 |
When doing a TFTP transfer and curl/libcurl is given a URL that contains a very long file name (longer than about 515 bytes), the file name is truncated to fit within the buffer boundaries, but the buffer size is still wrongly updated to use the untruncated length. This too large value is then used in the sendto() call, making curl attempt to send more data than what is actually put into the buffer. The endto() function will then read beyond the end of the heap based buffer. A malicious HTTP(S) server could redirect a vulnerable libcurl-using client to a crafted TFTP URL (if the client hasn't restricted which protocols it allows redirects to) and trick it to send private memory contents to a remote server over UDP. Limit curl's redirect protocols with --proto-redir and libcurl's with CURLOPT_REDIR_PROTOCOLS. Published: October 04, 2017; 9:29:04 PM -0400 |

CVE-2016-7167 |
Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl before 7.50.3 allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow.

V4.0:(not available) V3.0: 9.8 CRITICAL V2.0: 7.5 HIGH |
CVE-2016-7141 |
curl and libcurl before 7.50.2, when built with NSS and the libnsspem.so library is available at runtime, allow remote attackers to hijack the authentication of a TLS connection by leveraging reuse of a previously loaded client certificate from file for a connection for which no certificate has been set, a different vulnerability than CVE-2016-5420.

V4.0:(not available) V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2016-5421 |
Use-after-free vulnerability in libcurl before 7.50.1 allows attackers to control which connection is used or possibly have unspecified other impact via unknown vectors. Published: August 10, 2016; 10:59:06 AM -0400 |
V4.0:(not available) V3.1: 8.1 HIGH V2.0: 6.8 MEDIUM |
CVE-2016-5420 |
curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate. Published: August 10, 2016; 10:59:05 AM -0400 |
V4.0:(not available) V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2016-5419 |
curl and libcurl before 7.50.1 do not prevent TLS session resumption when the client certificate has changed, which allows remote attackers to bypass intended restrictions by resuming a session. Published: August 10, 2016; 10:59:03 AM -0400 |
