Debian DLA-375-1 : libpng Security Update
high Nessus Plugin ID 92678
Language:
Synopsis
The remote Debian host is missing a security update.Description
The remote Debian host is running a version of libpng prior to 1.2.44-1+squeeze6. It is, therefore, affected by the following vulnerabilities :- An out-of-bounds read error exists in the png_push_read_zTXt() function within file pngpread.c when decompressing PNG images. An unauthenticated, remote attacker can exploit this, via a large 'avail_in' field to cause a denial of service condition.
(CVE-2012-3425)
- A buffer overflow condition exists in the png_set_PLTE() function within file pngset.c and the png_get_PLTE() function within file pngget.c when handling bit-depth values less than 8. An unauthenticated, remote attacker can exploit this, via a specially crafted IHDR chunk in a PNG image, to cause a denial of service or have other unspecified impact. (CVE-2015-8472)
- An integer underflow condition exists in the png_check_keyword() function within file pngwutil.c. An unauthenticated, remote attacker can exploit this, via a specially crafted PNG image using a space character as a keyword, to cause a denial of service condition or other unspecified impact. (CVE-2015-8540)
