It was discovered that Jasper did not correctly handle corrupted JPEG2000
images. By tricking a user into opening a specially crafted JPG, a
remote attacker could cause the application using libjasper to crash,
resulting in a denial of service.
Sebastian Krahmer discovered that rsync contained an off-by-one
miscalculation when handling certain file paths. By creating a specially
crafted tree of files and tricking an rsync server into processing them,
a remote attacker could write a single NULL to stack memory, possibly
leading to arbitrary code execution.
Stefan Esser discovered that mod_status did not force a character set,
which could result in browsers becoming vulnerable to XSS attacks when
processing the output. If a user were tricked into viewing server
status output during a crafted server request, a remote attacker could
exploit this to modify the contents, or steal confidential data (such as
passwords), within the same domain. By default, mod_status is disabled
in Ubuntu.
David Thiel discovered that libvorbis did not correctly verify the size
of certain headers, and did not correctly clean up a broken stream.
If a user were tricked into processing a specially crafted Vorbis stream,
a remote attacker could execute arbitrary code with the user's privileges.
Several format string vulnerabilities have been discovered in Qt
warning messages. By causing an application to process specially
crafted input data which triggered Qt warnings, this could be
exploited to execute arbitrary code with the privilege of the user
running the application.
Derek Noonburg discovered an integer overflow in the Xpdf function
StreamPredictor::StreamPredictor(). By importing a specially crafted
PDF file into KWord, this could be exploited to run arbitrary code
with the user's privileges.
Sean Larsson discovered multiple integer overflows in Gimp. By tricking
a user into opening a specially crafted DICOM, PNM, PSD, PSP, RAS, XBM,
or XWD image, a remote attacker could exploit this to execute arbitrary
code with the user's privileges.
A flaw was discovered in handling of "about:blank" windows used by
addons. A malicious web site could exploit this to modify the contents,
or steal confidential data (such as passwords), of other web pages.
Jesper Johansson discovered that spaces and double-quotes were
not correctly handled when launching external programs. In rare
configurations, after tricking a user into opening a malicious web page,
an attacker could execute helpers with arbitrary arguments with the
user's privileges.
A flaw was discovered in the BGP dissector of tcpdump. Remote
attackers could send specially crafted packets and execute arbitrary
code with user privileges.
A flaw was discovered in Bind's sequence number generator. A remote
attacker could calculate future sequence numbers and send forged DNS
query responses. This could lead to client connections being directed
to attacker-controlled hosts, resulting in credential theft and other
attacks.
Various flaws were discovered in the layout and JavaScript engines. By
tricking a user into opening a malicious web page, an attacker could
execute arbitrary code with the user's privileges. (CVE-2007-3734,
USN-489-1 fixed vulnerabilities in the Linux kernel. This update
provides the corresponding fixes for the redhat cluster suite kernel
sources. A flaw was discovered in the cluster manager. A remote attacker could
connect to the DLM port and block further DLM operations.
A flaw was discovered in dvb ULE decapsulation. A remote attacker could
send a specially crafted message and cause a denial of service. The compat_sys_mount function allowed local users to cause a denial of service when mounting a smbfs filesystem in compatibility mode.
Alex Solovey discovered that mod_perl did not correctly validate certain
regular expression matches. A remote attacker could send a specially
crafted request to a web application using mod_perl, causing the web
server to monopolize CPU resources. This could lead to a remote denial
of service.
It was discovered that Dovecot, when configured to use non-system-user
spools and compressed folders, would allow directory traversals in
mailbox names. Remote authenticated users could potentially read email
owned by other users.
It was discovered that the PHP xmlrpc extension did not correctly check
heap memory allocation sizes. A remote attacker could send a specially
crafted request to a PHP application using xmlrpc and execute arbitrary
code as the Apache user.
It was discovered that the GnuTLS certificate verification methods
implemented in Curl did not check for expiration and activation dates.
When performing validations, tools using libcurl3-gnutls would
incorrectly allow connections to sites using expired certificates.
Peter Johannes Holzer discovered that the Net::DNS Perl module had
predictable sequence numbers. This could allow remote attackers to
carry out DNS spoofing, leading to possible man-in-the-middle attacks.
John Heasman discovered that OpenOffice did not correctly validate the
sizes of tags in RTF documents. If a user were tricked into opening a
specially crafted document, a remote attacker could execute arbitrary
code with user privileges.
