2012-09-14 CVE-2012-3955 Denial of Service vulnerability in ISC DHCP IPv6 Lease Expiration Handling
ISC DHCP 4.1.x before 4.1-ESV-R7 and 4.2.x before 4.2.4-P2 allows remote attackers to cause a denial of service (daemon crash) in opportunistic circumstances by establishing an IPv6 lease in an environment where the lease expiration time is later reduced.

2012-06-16 CVE-2011-4409 Improper Input Validation vulnerability in Canonical Ubuntu Linux
The Ubuntu One Client for Ubuntu 10.04 LTS, 11.04, 11.10, and 12.04 LTS does not properly validate SSL certificates, which allows remote attackers to spoof a server and modify or read sensitive information via a man-in-the-middle (MITM) attack.

2012-06-05 CVE-2012-1185 Integer Overflow or Wraparound vulnerability in multiple products
Multiple integer overflows in (1) magick/profile.c or (2) magick/property.c in ImageMagick 6.7.5 and earlier allow remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via crafted offset value in the ResolutionUnit tag in the EXIF IFD0 of an image.

2012-05-17 CVE-2012-0044 Integer Overflow or Wraparound vulnerability in multiple products
Integer overflow in the drm_mode_dirtyfb_ioctl function in drivers/gpu/drm/drm_crtc.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 3.1.5 allows local users to gain privileges or cause a denial of service (memory corruption) via a crafted ioctl call.

2011-11-29 CVE-2011-4405 Improper Input Validation vulnerability in Canonical Ubuntu Linux 11.04/11.10
The cupshelpers scripts in system-config-printer in Ubuntu 11.04 and 11.10, as used by the automatic printer driver download service, uses an "insecure connection" for queries to the OpenPrinting database, which allows remote attackers to execute arbitrary code via a man-in-the-middle (MITM) attack that modifies packages or repositories.

2011-10-10 CVE-2011-2189 Resource Exhaustion vulnerability in multiple products
net/core/net_namespace.c in the Linux kernel 2.6.32 and earlier does not properly handle a high rate of creation and cleanup of network namespaces, which makes it easier for remote attackers to cause a denial of service (memory consumption) via requests to a daemon that requires a separate namespace per connection, as demonstrated by vsftpd.

2011-08-15 CVE-2011-2749 Improper Input Validation vulnerability in multiple products
The server in ISC DHCP 3.x and 4.x before 4.2.2, 3.1-ESV before 3.1-ESV-R3, and 4.1-ESV before 4.1-ESV-R3 allows remote attackers to cause a denial of service (daemon exit) via a crafted BOOTP packet.

2011-07-18 CVE-2010-4656 Out-of-bounds Write vulnerability in multiple products
The iowarrior_write function in drivers/usb/misc/iowarrior.c in the Linux kernel before 2.6.37 does not properly allocate memory, which might allow local users to trigger a heap-based buffer overflow, and consequently cause a denial of service or gain privileges, via a long report.

2011-07-17 CVE-2011-2692 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
The png_handle_sCAL function in pngrutil.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 does not properly handle invalid sCAL chunks, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted PNG image that triggers the reading of uninitialized memory.
