The following table list reported vulnerabilities for the period covered by this report:
0 Critical Vulnerabilities
| DATE | CVE | VENDOR | VULNERABILITY | CVSS |

3 High Vulnerabilities
| DATE | CVE | VENDOR | VULNERABILITY | CVSS |
|---|---|---|---|---|
| 2011-07-17 | CVE-2011-2692 | Libpng Fedoraproject Debian Canonical | 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. | 8.8 |
| 2011-07-17 | CVE-2011-2690 | Libpng Fedoraproject Debian Canonical | Classic Buffer Overflow vulnerability in multiple products Buffer overflow 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, when used by an application that calls the png_rgb_to_gray function but not the png_set_expand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image. | 8.8 |
| 2011-07-13 | CVE-2011-1265 | Microsoft Bluetooth | Code Injection vulnerability in multiple products The Bluetooth Stack 2.1 in Microsoft Windows Vista SP1 and SP2 and Windows 7 Gold and SP1 does not prevent access to objects in memory that (1) were not properly initialized or (2) have been deleted, which allows remote attackers to execute arbitrary code via crafted Bluetooth packets, aka "Bluetooth Stack Vulnerability." | 8.8 |
2 Medium Vulnerabilities
| DATE | CVE | VENDOR | VULNERABILITY | CVSS |
|---|---|---|---|---|
| 2011-07-17 | CVE-2011-2691 | Libpng Fedoraproject Debian | NULL Pointer Dereference vulnerability in multiple products The png_err function in pngerror.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 makes a function call using a NULL pointer argument instead of an empty-string argument, which allows remote attackers to cause a denial of service (application crash) via a crafted PNG image. | 6.5 |
| 2011-07-17 | CVE-2011-2501 | Libpng Fedoraproject Debian Canonical | Out-of-bounds Read vulnerability in multiple products The png_format_buffer function in pngerror.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 allows remote attackers to cause a denial of service (application crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. | 6.5 |
