cURL: Multiple vulnerabilities


### Background cURL is a command line tool for transferring files with URL syntax, supporting numerous protocols. ### Description Multiple vulnerabilities have been found in cURL: * When zlib is enabled, the amount of data sent to an application for automatic decompression is not restricted (CVE-2010-0734). * When performing GSSAPI authentication, credential delegation is always used (CVE-2011-2192). * When SSL is enabled, cURL improperly disables the OpenSSL workaround to mitigate an information disclosure vulnerability in the SSL and TLS protocols (CVE-2011-3389). * libcurl does not properly verify file paths for escape control characters in IMAP, POP3 or SMTP URLs (CVE-2012-0036). ### Impact A remote attacker could entice a user or automated process to open a specially crafted file or URL using cURL, possibly resulting in the remote execution of arbitrary code, a Denial of Service condition, disclosure of sensitive information, or unwanted actions performed via the IMAP, POP3 or SMTP protocols. Furthermore, remote servers may be able to impersonate clients via GSSAPI requests. ### Workaround There is no known workaround at this time. ### Resolution All cURL users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/curl-7.24.0"
