Package : libpng
CVE ID : CVE-2015-7981 CVE-2015-8126
Debian Bug : 803078 805113
Several vulnerabilities have been discovered in the libpng PNG library.
The Common Vulnerabilities and Exposures project identifies the
following problems:
CVE-2015-7981
Qixue Xiao discovered an out-of-bounds read vulnerability in the
png_convert_to_rfc1123 function. A remote attacker can potentially
take advantage of this flaw to cause disclosure of information from
process memory.
CVE-2015-8126
Multiple buffer overflows were discovered in the png_set_PLTE and
png_get_PLTE functions. A remote attacker can take advantage of this
flaw to cause a denial of service (application crash) via a small
bit-depth value in an IHDR (image header) chunk in a PNG image.
For the oldstable distribution (wheezy), these problems have been fixed
in version 1.2.49-1+deb7u1.
For the stable distribution (jessie), these problems have been fixed in
version 1.2.50-2+deb8u1.
