Description

The remote host is affected by the vulnerability described in GLSA-201010-01 (Libpng: Multiple vulnerabilities)

Multiple vulnerabilities were found in libpng:
  The png_decompress_chunk() function in pngrutil.c does not properly         handle certain type of compressed data (CVE-2010-0205)       A buffer overflow in pngread.c when using progressive applications         (CVE-2010-1205)       A memory leak in pngrutil.c when dealing with a certain type of         chunks (CVE-2010-2249)   Impact :

An attacker could exploit these vulnerabilities to cause programs linked       against the library to crash or execute arbitrary code with the       permissions of the user running the vulnerable program, which could be       the root user.

Workaround :

There is no known workaround at this time.
