  script_tag(name:"insight", value:"Several vulnerabilities have been discovered in libpng, a library for reading and writing PNG files. The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2007-2445

The png_handle_tRNS function allows attackers to cause a denial of service (application crash) via a grayscale PNG image with a bad tRNS chunk CRC value.

CVE-2007-5269

Certain chunk handlers allow attackers to cause a denial of service (crash) via crafted pCAL, sCAL, tEXt, iTXt, and ztXT chunking in PNG images, which trigger out-of-bounds read operations.

CVE-2008-1382

libpng allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a PNG file with zero length 'unknown' chunks, which trigger an access of uninitialized memory.

CVE-2008-5907

The png_check_keyword might allow context-dependent attackers to set the value of an arbitrary memory location to zero via vectors involving creation of crafted PNG files with keywords.

CVE-2008-6218

A memory leak in the png_handle_tEXt function allows context-dependent attackers to cause a denial of service (memory exhaustion) via a crafted PNG file.

CVE-2009-0040

libpng allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file that triggers a free of an uninitialized pointer in (1) the png_read_png function, (2) pCAL chunk handling, or (3) setup of 16-bit gamma tables.

For the old stable distribution (etch), these problems have been fixed in version 1.2.15~beta5-1+etch2.

For the stable distribution (lenny), these problems have been fixed in version 1.2.27-2+lenny2. (Only CVE-2008-5907, CVE-2008-5907 and CVE-2009-0040 affect the stable distribution.)

For the unstable distribution (sid), these problems have been fixed in version 1.2.35-1.

We recommend that you upgrade your libpng packages.");
