| CVE-2018-1000030 | 2 Canonical, Python | 2 Ubuntu Linux, Python | 2024-11-21 | 3.6 Low |
| Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. So when a large amount of data is being processed, it is very easy to cause memory corruption using a Heap-Buffer-Overflow. As for the Use-After-Free, Thread3->Malloc->Thread1->Free's->Thread2-Re-uses-Free'd Memory. The PSRT has stated that this is not a security vulnerability due to the fact that the attacker must be able to run code, however in some situations, such as function as a service, this vulnerability can potentially be used by an attacker to violate a trust boundary, as such the DWF feels this issue deserves a CVE. | ||||

| CVE-2018-1000007 | 5 Canonical, Debian, Fujitsu and 2 more | 27 Ubuntu Linux, Debian Linux, M10-1 and 24 more | 2024-11-21 | 9.8 Critical |
| 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 follow redirects and a 30X HTTP response code is returned, to the host mentioned in URL in the `Location:` response header value. Sending the same set of headers to subsequent hosts is in particular a problem for applications that pass on custom `Authorization:` headers, as this header often contains privacy sensitive information or data that could allow others to impersonate the libcurl-using client's request. | ||||
| CVE-2018-1000005 | 4 Canonical, Debian, Haxx and 1 more | 4 Ubuntu Linux, Debian Linux, Libcurl and 1 more | 2024-11-21 | N/A |
| 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 one byte less than required. The problem is that the code that creates HTTP/1-like headers from the HTTP/2 trailer data once appended a string like `:` to the target buffer, while this was recently changed to `: ` (a space was added after the colon) but the following math wasn't updated correspondingly. When accessed, the data is read out of bounds and causes either a crash or that the (too large) data gets passed to client write. This could lead to a denial-of-service situation or an information disclosure if someone has a service that echoes back or uses the trailers for something. | ||||
| CVE-2018-1000001 | 3 Canonical, Gnu, Redhat | 10 Ubuntu Linux, Glibc, Enterprise Linux and 7 more | 2024-11-21 | N/A |
| In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to write before the destination buffer leading to a buffer underflow and potential code execution. | ||||
| CVE-2018-0739 | 4 Canonical, Debian, Openssl and 1 more | 6 Ubuntu Linux, Debian Linux, Openssl and 3 more | 2024-11-21 | N/A |
| Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n). | ||||
| CVE-2018-0737 | 3 Canonical, Openssl, Redhat | 4 Ubuntu Linux, Openssl, Enterprise Linux and 1 more | 2024-11-21 | N/A |
| The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack.

| CVE-2018-0734 | 7 Canonical, Debian, Netapp and 4 more | 23 Ubuntu Linux, Debian Linux, Cloud Backup and 20 more | 2024-11-21 | 5.9 Medium |
| The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p). | ||||
| CVE-2018-0732 | 5 Canonical, Debian, Nodejs and 2 more | 7 Ubuntu Linux, Debian Linux, Node.js and 4 more | 2024-11-21 | 7.5 High |
| During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2-1.0.2o). | ||||
