Curl versions 7.33.0 through 7.61.1 are vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service.
CVE-2019-3822 4 Haxx, Canonical, Debian and 1 more 4 Libcurl, Ubuntu Linux, Debian Linux and 1 more 2019-04-09 7.5
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header...
CVE-2018-16890 4 Haxx, Canonical, Debian and 1 more 4 Libcurl, Ubuntu Linux, Debian Linux and 1 more 2019-04-09 5.0
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is...
CVE-2018-14618 4 Haxx, Canonical, Debian and 1 more 4 Libcurl, Ubuntu Linux, Debian Linux and 1 more 2019-04-09 10.0
curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to...
CVE-2018-1000007 4 Haxx, Debian, Canonical and 1 more 6 Curl, Debian Linux, Ubuntu Linux and 3 more 2019-03-25 5.0
libcurl 7.1 through 7.57.0 might accidentally leak authentication data to third parties. When asked to send custom headers in its HTTP requests, libcurl will send that set of headers first to the host in the initial URL but also, if asked to...
CVE-2018-1000005 3 Haxx, Debian, Canonical 3 Libcurl, Debian Linux, Ubuntu Linux 2019-03-25 6.4
libcurl 7.49.0 to and including 7.57.0 contains an out bounds read in code handling HTTP/2 trailers. It was reported (https://github.com/curl/curl/pull/2231) that reading an HTTP/2 trailer could mess up future trailers since the stored size was...
CVE-2019-3823 4 Haxx, Canonical, Debian and 1 more 4 Libcurl, Ubuntu Linux, Debian Linux and 1 more 2019-03-18 5.0
libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the...
CVE-2018-16842 3 Haxx, Canonical, Debian 3 Curl, Ubuntu Linux, Debian Linux 2019-03-11 6.4
Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.
CVE-2018-16840 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2019-03-11 7.5
A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the `Curl_close()` function, the library code first frees a struct...
CVE-2018-1000301 3 Haxx, Canonical, Debian 3 Curl, Ubuntu Linux, Debian Linux 2019-01-16 6.4
curl version curl 7.20.0 to and including curl 7.59.0 contains a CWE-126: Buffer Over-read vulnerability in denial of service that can result in curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded...
CVE-2018-1000300 2 Haxx, Canonical 2 Curl, Ubuntu Linux 2019-01-16 7.5
curl version curl 7.54.1 to and including curl 7.59.0 contains a CWE-122: Heap-based Buffer Overflow vulnerability in denial of service and more that can result in curl might overflow a heap based memory buffer when closing down an FTP connection...
CVE-2018-1000122 3 Haxx, Canonical, Debian 3 Curl, Ubuntu Linux, Debian Linux 2019-01-16 6.4
A buffer over-read exists in curl 7.20.0 to and including curl 7.58.0 in the RTSP+RTP handling code that allows an attacker to cause a denial of service or information leakage
CVE-2018-1000121 3 Haxx, Canonical, Debian 3 Curl, Ubuntu Linux, Debian Linux 2019-01-16 5.0
A NULL pointer dereference exists in curl 7.21.0 to and including curl 7.58.0 in the LDAP code that allows an attacker to cause a denial of service
CVE-2018-1000120 3 Haxx, Canonical, Debian 3 Curl, Ubuntu Linux, Debian Linux 2019-01-16 7.5
A buffer overflow exists in curl 7.12.3 to and including curl 7.58.0 in the FTP URL handling that allows an attacker to cause a denial of service or worse.
CVE-2017-8817 2 Haxx, Debian 3 Curl, Libcurl, Debian Linux 2018-11-13 7.5
The FTP wildcard function in curl and libcurl before 7.57.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) or possibly have unspecified other impact via a string that ends with an '[' character.
CVE-2017-8816 2 Haxx, Debian 3 Curl, Libcurl, Debian Linux 2018-11-13 7.5
The NTLM authentication feature in curl and libcurl before 7.57.0 on 32-bit platforms allows attackers to cause a denial of service (integer overflow and resultant buffer overflow, and application crash) or possibly have unspecified other impact...
