- ------------------------------------------------------------------------- Debian Security Advisory DSA-3399-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso November 18, 2015 https://www.debian.org/security/faq - -------------------------------------------------------------------------
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.
For the unstable distribution (sid), these problems have been fixed in version 1.2.54-1.
We recommend that you upgrade your libpng packages.
