Fedoraproject Fedora 21

A flaw was found in the default configuration of dnsmasq, as shipped with Fedora versions prior to 31 and in all versions Red Hat Enterprise Linux, where it listens on any interface and accepts queries from addresses outside of its local subnet. In particular, the option `local-service` is not enabled. Running dnsmasq in this manner may inadvertently make it an open resolver accessible from any address on the internet. This flaw allows an attacker to conduct a Distributed Denial of Service (DDoS) against other systems.

The Moped::BSON::ObjecId.legal? method in mongodb/bson-ruby before 3.0.4 as used in rubygem-moped allows remote attackers to cause a denial of service (worker resource consumption) via a crafted string. NOTE: This issue is due to an incomplete fix to CVE-2015-4410.

The Moped::BSON::ObjecId.legal? method in rubygem-moped before commit dd5a7c14b5d2e466f7875d079af71ad19774609b allows remote attackers to cause a denial of service (worker resource consumption) or perform a cross-site scripting (XSS) attack via a crafted string.

SQL injection vulnerability in Zend Framework before 1.12.9, 2.2.x before 2.2.8, and 2.3.x before 2.3.3, when using the sqlsrv PHP extension, allows remote attackers to execute arbitrary SQL commands via a null byte.

A NULL pointer dereference flaw was found in the way LibVNCServer before 0.9.9 handled certain ClientCutText message. A remote attacker could use this flaw to crash the VNC server by sending a specially crafted ClientCutText message from a VNC client.

The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service (infinite loop and guest crash) via unspecified vectors.

Buffer overflow in the send_control_msg function in hw/char/virtio-serial-bus.c in QEMU before 2.4.0 allows guest users to cause a denial of service (QEMU process crash) via a crafted virtio control message.

The ne2000_receive function in hw/net/ne2000.c in QEMU before 2.4.0.1 allows attackers to cause a denial of service (infinite loop and instance crash) or possibly execute arbitrary code via vectors related to receiving packets.

Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop.

Cross-site scripting (XSS) vulnerability in templates/openid-selector.tmpl in ikiwiki before 3.20150329 allows remote attackers to inject arbitrary web script or HTML via the openid_identifier parameter in a verify action to ikiwiki.cgi.

The mirroring support (-M, --use-mirrors) in Python Pip before 1.5 uses insecure DNS querying and authenticity checks which allows attackers to perform man-in-the-middle attacks.

Simple Desktop Display Manager (SDDM) before 0.10.0 allows local users to gain root privileges because code running as root performs write operations within a user home directory, and this user may have created links in advance (exploitation requires the user to win a race condition in the ~/.Xauthority chown case, but not other cases).

Simple Desktop Display Manager (SDDM) before 0.10.0 allows local users to log in as user "sddm" without authentication.

The OAuth extension for MediaWiki improperly negotiates a new client token only over Special:OAuth/initiate, which allows attackers to bypass intended IP address access restrictions by making an API request with an existing token.

The find_ifcfg_path function in netcf before 0.2.7 might allow attackers to cause a denial of service (application crash) via vectors involving augeas path expressions.

The net/http library in net/http/transfer.go in Go before 1.4.3 does not properly parse HTTP headers, which allows remote attackers to conduct HTTP request smuggling attacks via a request with two Content-length headers.

The net/http library in net/textproto/reader.go in Go before 1.4.3 does not properly parse HTTP header keys, which allows remote attackers to conduct HTTP request smuggling attacks via a space instead of a hyphen, as demonstrated by "Content Length" instead of "Content-Length."

libjpeg-turbo before 1.3.1 allows remote attackers to cause a denial of service (crash) via a crafted JPEG file, related to the Exif marker.

The (1) filesystem::get_wml_location function in filesystem.cpp and (2) is_legal_file function in filesystem_boost.cpp in Battle for Wesnoth before 1.12.4 and 1.13.x before 1.13.1, when a case-insensitive filesystem is used, allow remote attackers to obtain sensitive information via vectors related to inclusion of .pbl files from WML. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-5069.

The (1) filesystem::get_wml_location function in filesystem.cpp and (2) is_legal_file function in filesystem_boost.cpp in Battle for Wesnoth before 1.12.3 and 1.13.x before 1.13.1 allow remote attackers to obtain sensitive information via vectors related to inclusion of .pbl files from WML.

scripts/licensecheck.pl in devscripts before 2.15.7 allows local users to execute arbitrary shell commands.

Cross-site request forgery in the REST API in IPython 2 and 3.

The ssl-proxy-openssl.c function in Dovecot before 2.2.17, when SSLv3 is disabled, allow remote attackers to cause a denial of service (login process crash) via vectors related to handshake failures.

Argument injection vulnerability in devscripts before 2.15.7 allows remote attackers to write to arbitrary files via a crafted symlink and crafted filename.

Directory traversal vulnerability in GNU patch versions which support Git-style patching before 2.7.3 allows remote attackers to write to arbitrary files with the permissions of the target user via a .. (dot dot) in a diff file name.
