Summary

curl before version 7.52.0 is vulnerable to a buffer overflow when doing a large floating point output in libcurl's implementation of the printf() functions. If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks.

Common Weakness Enumeration (CWE)

CWE-122 - Heap-based Buffer Overflow

Common Attack Pattern Enumeration and Classification (CAPEC)

Forced Integer Overflow
This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.

When libcurl connects to an FTP server and successfully logs in (anonymous or not), it asks the server for the current directory with the `PWD` command. The server then responds with a 257 response containing the path, inside double quotes. The returned path name is then kept by libcurl for subsequent uses. Due to a flaw in the string parser for this directory name, a directory name passed like this but without a closing double quote would lead to libcurl not adding a trailing NUL byte to the buffer holding the name. When libcurl would then later access the string, it could read beyond the allocated heap buffer and crash or wrongly access data beyond the buffer, thinking it was part of the path. A malicious server could abuse this fact and effectively prevent libcurl-based clients to work with it - the PWD command is always issued on new FTP connections and the mistake has a high chance of causing a segfault. The simple fact that this has issue remained undiscovered for this long could suggest that malformed PWD responses are rare in benign servers. We are not aware of any exploit of this flaw. This bug was introduced in commit [415d2e7cb7](https://github.com/curl/curl/commit/415d2e 7cb7), March 2005. In libcurl version 7.56.0, the parser always zero terminates the string but also rejects it if not terminated properly with a final double quote.i1/4^CVE-2017-1000254i1/4%0 - 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

description	The remote host is running Mac OS X 10.10.5, Mac OS X 10.11.6, or macOS 10.12.5 and is missing a security update. It is therefore, affected by multiple vulnerabilities : - An overflow condition exists in the curl component in the dprintf_formatf() function that is triggered when handling floating point conversion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9586) - A flaw exits in the curl component in the randit() function within file lib/rand.c due to improper initialization of the 32-bit random value, which is used, for example, to generate Digest and NTLM authentication nonces, resulting in weaker cryptographic operations than expected. (CVE-2016-9594) - A flaw exists in the curl component in the allocate_conn() function in lib/url.c when using the OCSP stapling feature for checking a X.509 certificate revocation status. The issue is triggered as the request option for OCSP stapling is not properly passed to the TLS library, resulting in no error being returned even when no proof of the validity of the certificate could be provided. A man-in-the-middle attacker can exploit this to provide a revoked certificate. (CVE-2017-2629) - A remote code execution vulnerability exists in the CoreAudio component due to improper validation of user-supplied input when handling movie files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted movie file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7008) - A memory corruption issue exists in the IOUSBFamily component due to improper validation of user-supplied input. A local attacker can exploit this, via a specially crafted application, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7009) - Multiple out-of-bounds read errors exist in the libxml2 component due to improper handling of specially crafted XML documents. An unauthenticated, remote attacker can exploit these to disclose user information. (CVE-2017-7010, CVE-2017-7013) - Multiple memory corruption issues exist in the Intel Graphics Driver component due to improper validation of input. A local attacker can exploit these issues to execute arbitrary code with elevated privileges.
