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 : perl (ALAS-2011-19)

A heap-based buffer overflow flaw was found in the way Perl decoded Unicode strings. An attacker could create a malicious Unicode string that, when decoded by a Perl program, would cause the program to crash or, potentially, execute arbitrary code with the permissions of the user running the...

Amazon Linux AMI : icu (ALAS-2012-33)

A stack-based buffer overflow flaw was found in the way ICU performed variant canonicalization for some locale identifiers. If a specially crafted locale representation was opened in an application linked against ICU, it could cause the application to crash or, possibly, execute arbitrary code wi...

Amazon Linux AMI : libxslt (ALAS-2012-123)

A heap-based buffer overflow flaw was found in the way libxslt applied templates to nodes selected by certain namespaces. An attacker could use this flaw to create a malicious XSL file that, when used by an application linked against libxslt to perform an XSL transformation, could cause the...

Amazon Linux AMI : php (ALAS-2012-37)

It was found that the hashing routine used by PHP arrays was susceptible to predictable hash collisions. If an HTTP POST request to a PHP application contained many parameters whose names map to the same hash value, a large amount of CPU time would be consumed. This flaw has been mitigated by...

Amazon Linux AMI : postgresql (ALAS-2011-12)

A signedness issue was found in the way the crypt function in the PostgreSQL pgcrypto module handled 8-bit characters in passwords when using Blowfish hashing. Up to three characters immediately preceding a non-ASCII character one with the high bit set had no effect on the hash result, thus...

Amazon Linux AMI : rsyslog (ALAS-2012-105)

A numeric truncation error, leading to a heap-based buffer overflow, was found in the way the rsyslog imfile module processed text files containing long lines. An attacker could use this flaw to crash the rsyslogd daemon or, possibly, execute arbitrary code with the privileges of rsyslogd, if the...

Amazon Linux AMI : libxml2 (ALAS-2012-36)

A heap-based buffer overflow flaw was found in the way libxml2 decoded entity references with long names. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrar...

Amazon Linux AMI : krb5 (ALAS-2011-28)

A NULL pointer dereference flaw was found in the way the MIT Kerberos KDC processed certain TGS Ticket-granting Server requests. A remote, authenticated attacker could use this flaw to crash the KDC via a specially crafted TGS request. CVE-2011-1530 C Tenable Network Security, Inc. The descriptiv...

Amazon Linux AMI : cyrus-imapd (ALAS-2011-27)

An authentication bypass flaw was found in the cyrus-imapd NNTP server, nntpd. A remote user able to use the nntpd service could use this flaw to read or post newsgroup messages on an NNTP server configured to require user authentication, without providing valid authentication credentials...

Amazon Linux AMI : dhcp (ALAS-2012-31)

A denial of service flaw was found in the way the dhcpd daemon handled DHCP request packets when regular expression matching was used in '/etc/dhcp/dhcpd.conf'. A remote attacker could use this flaw to crash dhcpd. CVE-2011-4539 C Tenable Network Security, Inc. The descriptive text and package...

Amazon Linux AMI : ruby (ALAS-2013-173)

It was discovered that Ruby's REXML library did not properly restrict XML entity expansion. An attacker could use this flaw to cause a denial of service by tricking a Ruby application using REXML to read text nodes from specially crafted XML content, which will result in REXML consuming large...

Amazon Linux AMI : tomcat6 (ALAS-2011-25)

Certain AJP protocol connector implementations in Apache Tomcat 7.0.0 through 7.0.20, 6.0.0 through 6.0.33, 5.5.0 through 5.5.33, and possibly other versions allow remote attackers to spoof AJP requests, bypass authentication, and obtain sensitive information by causing the connector to interpret...

Amazon Linux AMI : openssh (ALAS-2012-99)

A denial of service flaw was found in the OpenSSH GSSAPI authentication implementation. A remote, authenticated user could use this flaw to make the OpenSSH server daemon sshd use an excessive amount of memory, leading to a denial of service. GSSAPI authentication is enabled by default...

Amazon Linux AMI : libpng (ALAS-2012-49)

A heap-based buffer overflow flaw was found in libpng. An attacker could create a specially crafted PNG image that, when opened, could cause an application using libpng to crash or, possibly, execute arbitrary code with the privileges of the user running the application. CVE-2011-3026 C Tenable...

Amazon Linux AMI : pam (ALAS-2013-160)

A stack-based buffer overflow flaw was found in the way the pamenv module parsed users' '/.pamenvironment' files. If an application's PAM configuration contained 'userreadenv=1' this is not the default, a local attacker could use this flaw to crash the application or, possibly, escalate their...

Amazon Linux AMI : libxml2 (ALAS-2012-134)

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way libxml2 handled documents that enable entity expansion. A remote attacker could provide a large, specially crafted XML file that, when opened in an application linked against libxml2, would cause the...

Amazon Linux AMI : httpd (ALAS-2012-46)

It was discovered that the fix for CVE-2011-3368 did not completely address the problem. An attacker could bypass the fix and make a reverse proxy connect to an arbitrary server not directly accessible to the attacker by sending an HTTP version 0.9 request, or by using a specially crafted URI...

Amazon Linux AMI : cyrus-impad (ALAS-2011-02)

The MITRE CVE database describes CVE-2011-3208 as : A buffer overflow flaw was found in the cyrus-imapd NNTP server, nntpd. A remote user able to use the nntpd service could use this flaw to crash the nntpd child process or, possibly, execute arbitrary code with the privileges of the cyrus user. ...
