Amazon Linux AMI : python-crypto (ALAS-2012-86)

PyCrypto before 2.6 does not produce appropriate prime numbers when using an ElGamal scheme to generate a key, which reduces the signature space or public key space and makes it easier for attackers to conduct brute-force attacks to obtain the private key. C Tenable Network Security, Inc. The...

Amazon Linux AMI : wireshark (ALAS-2012-71)

Several flaws were found in Wireshark. If Wireshark read a malformed packet off a network or opened a malicious dump file, it could crash or, possibly, execute arbitrary code as the user running Wireshark. Several denial of service flaws were found in Wireshark. Wireshark could crash or stop...

Amazon Linux AMI : jasper (ALAS-2011-29)

Two heap-based buffer overflow flaws were found in the way JasPer decoded JPEG 2000 compressed image files. An attacker could create a malicious JPEG 2000 compressed image file that, when opened, would cause applications that use JasPer such as Nautilus to crash or, potentially, execute arbitrary...

Amazon Linux AMI : libpng (ALAS-2012-56)

A heap-based buffer overflow flaw was found in the way libpng processed compressed chunks in PNG image files. An attacker could create a specially crafted PNG image file that, when opened, could cause an application using libpng to crash or, possibly, execute arbitrary code with the privileges of...

Amazon Linux AMI : openssl098e (ALAS-2012-73)

Multiple numeric conversion errors, leading to a buffer overflow, were found in the way OpenSSL parsed ASN.1 Abstract Syntax Notation One data from BIO OpenSSL's I/O abstraction inputs. Specially crafted DER Distinguished Encoding Rules encoded data read from a file or other BIO input could cause...

Amazon Linux AMI : python26 (ALAS-2012-98)

A denial of service flaw was found in the implementation of associative arrays dictionaries in Python. An attacker able to supply a large number of inputs to a Python application such as HTTP POST request parameters sent to a web application that are used as keys when inserting data into an array...

Amazon Linux AMI : perl-YAML-LibYAML (ALAS-2012-69)

Multiple format string vulnerabilities in the error reporting functionality in the YAML::LibYAML aka YAML-LibYAML and perl-YAML-LibYAML module 0.38 for Perl allow remote attackers to cause a denial of service process crash via format string specifiers in a 1 YAML stream to the Load function, 2 YA...

Amazon Linux AMI : axis (ALAS-2013-164)

Apache Axis did not verify that the server hostname matched the domain name in the subject's Common Name CN or subjectAltName field in X.509 certificates. This could allow a man-in-the-middle attacker to spoof an SSL server if they had a certificate that was valid for any domain name. CVE-2012-57...

Amazon Linux AMI : nss (ALAS-2013-149)

It was found that a Certificate Authority CA mis-issued two intermediate certificates to customers. These certificates could be used to launch man-in-the-middle attacks. This update renders those certificates as untrusted. This covers all uses of the certificates, including SSL, S/MIME, and code...

Amazon Linux AMI : lighttpd (ALAS-2012-107)

Integer signedness error in the base64decode function in the HTTP authentication functionality httpauth.c in lighttpd 1.4 before 1.4.30 and 1.5 before SVN revision 2806 allows remote attackers to cause a denial of service segmentation fault via crafted base64 input that triggers an out-of-bounds...

Amazon Linux AMI : net-snmp (ALAS-2012-97)

An array index error, leading to an out-of-bounds buffer read flaw, was found in the way the net-snmp agent looked up entries in the extension table. A remote attacker with read privileges to a Management Information Base MIB subtree handled by the 'extend' directive in '/etc/snmp/snmpd.conf' cou...

Amazon Linux AMI : lighttpd (ALAS-2013-179)

The httprequestsplitvalue function in request.c in lighttpd before 1.4.32 allows remote attackers to cause a denial of service infinite loop via a request with a header containing an empty token, as demonstrated using the 'Connection: TE,,Keep-Alive' header. C Tenable Network Security, Inc. The...

Amazon Linux AMI : iproute (ALAS-2012-64)

iproute2 before 3.3.0 allows local users to overwrite arbitrary files via a symlink attack on a temporary file used by 1 configure or 2 examples/dhcp-client-script. C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from Amazon Linux AMI Securit...

Amazon Linux AMI : ca-certificates (ALAS-2011-03)

This update includes the latest updates to the root Certificate Authority list from Mozilla. It was found that a Certificate Authority CA issued fraudulent HTTPS certificates. This update removes that CA's root certificate from the ca-certificates package, rendering any HTTPS certificates signed ...

Amazon Linux AMI : rpm (ALAS-2011-14)

Multiple flaws were found in the way the RPM library parsed package headers. An attacker could create a specially crafted RPM package that, when queried or installed, would cause rpm to crash or, potentially, execute arbitrary code. CVE-2011-3378 C Tenable Network Security, Inc. The descriptive...

Amazon Linux AMI : tomcat7 (ALAS-2013-191)

java/org/apache/catalina/core/AsyncContextImpl.java in Apache Tomcat 7.x before 7.0.40 does not properly handle the throwing of a RuntimeException in an AsyncListener in an application, which allows context-dependent attackers to obtain sensitive request information intended for other application...

Amazon Linux AMI : perl-libwww-perl (ALAS-2011-17)

The Net::HTTPS module in libwww-perl LWP before 6.00, as used in WWW::Mechanize, LWP::UserAgent, and other products, when running in environments that do not set the If-SSL-Cert-Subject header, does not enable full validation of SSL certificates by default, which allows remote attackers to spoof...

Amazon Linux AMI : dbus (ALAS-2012-128)

It was discovered that the D-Bus library honored environment settings even when running with elevated privileges. A local attacker could possibly use this flaw to escalate their privileges, by setting specific environment variables before running a setuid or setgid application linked against the...

Amazon Linux AMI : perl-DBD-Pg (ALAS-2012-112)

Two format string flaws were found in perl-DBD-Pg. A specially crafted database warning or error message from a server could cause an application using perl-DBD-Pg to crash or, potentially, execute arbitrary code with the privileges of the user running the application. CVE-2012-1151 C Tenable...

Amazon Linux AMI : bind (ALAS-2012-146)

A flaw was found in the DNS64 implementation in BIND. If a remote attacker sent a specially crafted query to a named server, named could exit unexpectedly with an assertion failure. Note that DNS64 support is not enabled by default. CVE-2012-5688 C Tenable Network Security, Inc. The descriptive...
