Jose Ramon Palanco discovered that the mono System.Web class did not consistently verify local file paths. As a result, the source code for mono web applications could be retrieved remotely, possibly leading to further compromise via the application's source.
A format string vulnerability was discovered in the gdmchooser component of the GNOME Display Manager. By typing a specially crafted host name, local users could gain gdm user privileges, which could lead to further account information exposure.
USN-380-1 fixed a vulnerability in Avahi. However, if used with Network manager, that version occasionally failed to resolve .local DNS names until Avahi got restarted. This update fixes the problem. We apologize for the inconvenience.
The following CVEIDs are covered by this advisory: CVE-2006-4572, CVE-2006-4813, CVE-2006-4997, CVE-2006-5158, CVE-2006-5173, CVE-2006-5619, CVE-2006-5648, CVE-2006-5649, CVE-2006-5701, CVE-2006-5751
An error was found in Ruby's CGI library that did not correctly quote the boundary of multipart MIME requests. Using a crafted HTTP request, a remote user could cause a denial of service, where Ruby CGI applications would end up in a loop, monopolizing a CPU.
USN-389-1 and USN-393-1 fixed vulnerabilities in gnupg. This update provides the corresponding updates for gnupg2.
Tavis Ormandy discovered that gnupg was incorrectly using the stack. If a user were tricked into processing a specially crafted message, an attacker could execute arbitrary code with the user's privileges.
USN-390-2 fixed vulnerabilities in evince. This update provides the corresponding update for evince-gtk.
USN-390-1 fixed a vulnerability in evince. The original fix did not fully solve the problem, allowing for a denial of service in certain situations.
A heap overflow was discovered in the OLE processing code in libgsf. If a user were tricked into opening a specially crafted OLE document, an attacker could execute arbitrary code with the user's privileges.
A buffer overflow was discovered in the Real Media input plugin in xine-lib. If a user were tricked into loading a specially crafted stream from a malicious server, the attacker could execute arbitrary code with the user's privileges.
A buffer overflow was discovered in the PostScript processor included in evince. By tricking a user into opening a specially crafted PS file, an attacker could crash evince or execute arbitrary code with the user's privileges.
A buffer overflow was discovered in GnuPG. By tricking a user into running gpg interactively on a specially crafted message, an attacker could execute arbitrary code with the user's privileges. This vulnerability is not exposed when running gpg in batch mode.
Daniel Kobras discovered multiple buffer overflows in ImageMagick's SGI file format decoder. By tricking a user or an automated system into processing a specially crafted SGI image, this could be exploited to execute arbitrary code with the user's privileges.
USN-352-1 fixed a flaw in the verification of PKCS certificate signatures. Ulrich Kuehn discovered a variant of the original attack which the original fix did not cover. (CVE-2006-5462) Various flaws have been reported that allow an attacker to execute arbitrary code with user privileges by tricking the user into opening a malicious email containing JavaScript. Please note that JavaScript is disabled by default for emails, and it is not recommended to enable it. (CVE-2006-5463, CVE-2006-5464, CVE-2006-5747, CVE-2006-5748)
USN-351-1 fixed a flaw in the verification of PKCS certificate signatures. Ulrich Kuehn discovered a variant of the original attack which the original fix did not cover. (CVE-2006-5462) Various flaws have been reported that allow an attacker to execute arbitrary code with user privileges by tricking the user into opening a malicious web page containing JavaScript. (CVE-2006-5463, CVE-2006-5464, CVE-2006-5747, CVE-2006-5748)
Evgeny Legerov discovered that the OpenLDAP libraries did not correctly truncate authcid names. This situation would trigger an assert and abort the program using the libraries. A remote attacker could send specially crafted bind requests that would lead to an LDAP server denial of service.
Tavis Ormandy discovered that libpng did not correctly calculate the size of sPLT structures when reading an image. By tricking a user or an automated system into processing a specially crafted PNG file, an attacker could exploit this weakness to crash the application using the library.
Steve Grubb discovered that netlink messages were not being checked for their sender identity. This could lead to local users manipulating the Avahi service.
Miloslav Trmac discovered a buffer overflow in texinfo's index processor. If a user is tricked into processing a .texi file with texindex, this could lead to arbitrary code execution with user privileges.
