Gentoo Linux Security Advisory
Title: cURL: Multiple vulnerabilities (GLSA 201203-02)
Severity: normal
Exploitable: remote
Date: March 06, 2012
Bug(s): #308645, #373235, #400799
ID: 201203-02
Synopsis
Multiple vulnerabilities have been found in cURL, the worst of
which might allow remote execution of arbitrary code.
Background
cURL is a command line tool for transferring files with URL syntax,
supporting numerous protocols.
Affected Packages
Package: net-misc/curl
Vulnerable: < 7.24.0
Unaffected: >= 7.24.0
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.24.0"
