Ubuntu Security Notice USN-1513-1
July 23, 2012
libexif vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS
Summary:
libexif could be made to crash, run programs as your login, or expose
sensitive information if it opened a specially crafted file.
Software Description:
- libexif: library to parse EXIF files
Details:
Mateusz Jurczyk discovered that libexif incorrectly parsed certain
malformed EXIF tags. If a user or automated system were tricked into
processing a specially crafted image file, an attacker could cause libexif
to crash, leading to a denial of service, or possibly obtain sensitive
information. (CVE-2012-2812, CVE-2012-2813)
Mateusz Jurczyk discovered that libexif incorrectly parsed certain
malformed EXIF tags. If a user or automated system were tricked into
processing a specially crafted image file, an attacker could cause libexif
to crash, leading to a denial of service, or possibly execute arbitrary
code. (CVE-2012-2814)
Yunho Kim discovered that libexif incorrectly parsed certain malformed EXIF
tags. If a user or automated system were tricked into processing a
specially crafted image file, an attacker could cause libexif to crash,
leading to a denial of service, or possibly obtain sensitive information.
(CVE-2012-2836)
Yunho Kim discovered that libexif incorrectly parsed certain malformed EXIF
tags. If a user or automated system were tricked into processing a
specially crafted image file, an attacker could cause libexif to crash,
leading to a denial of service. (CVE-2012-2837)
Dan Fandrich discovered that libexif incorrectly parsed certain malformed
EXIF tags. If a user or automated system were tricked into processing a
specially crafted image file, an attacker could cause libexif to crash,
leading to a denial of service, or possibly execute arbitrary code.
(CVE-2012-2840, CVE-2012-2841)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
libexif12 0.6.20-2ubuntu0.1
Ubuntu 11.10:
libexif12 0.6.20-1ubuntu0.1
Ubuntu 11.04:
libexif12 0.6.20-0ubuntu1.1
Ubuntu 10.04 LTS:
libexif12 0.6.19-1ubuntu0.1
Ubuntu 8.04 LTS:
libexif12 0.6.16-2.1ubuntu0.2
In general, a standard system update will make all the necessary changes.

Ubuntu Security Notice USN-1515-1
July 23, 2012
linux vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
The system could be made to crash under certain conditions.
Software Description:
- linux: Linux kernel
Details:
An error was discovered in the Linux kernel's memory subsystem (hugetlb).
An unprivileged local user could exploit this flaw to cause a denial of
service (crash the system).
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
linux-image-3.2.0-27-generic 3.2.0-27.43
linux-image-3.2.0-27-generic-pae 3.2.0-27.43
linux-image-3.2.0-27-highbank 3.2.0-27.43
linux-image-3.2.0-27-omap 3.2.0-27.43
linux-image-3.2.0-27-powerpc-smp 3.2.0-27.43
linux-image-3.2.0-27-powerpc64-smp 3.2.0-27.43
linux-image-3.2.0-27-virtual 3.2.0-27.43
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
