CVE-2015-7981

The png_convert_to_rfc1123 function in png.c in libpng 1.0.x before 1.0.64, 1.2.x before 1.2.54, and 1.4.x before 1.4.17 allows remote attackers to obtain sensitive process memory information via crafted tIME chunk data in an image file, which triggers an out-of-bounds read.

An out-of-bounds read in png_convert_to_rfc1123() in png.c in libpng 1.2.x before 1.2.54 could potentially be exploited by a crafted PNG file to leak information from an application's memory (CVE-2015-7981).

These are all security issues fixed in the libvlc5-2.2.4-11.1 package on the GA media of openSUSE Tumbleweed.

The libpng12-0 package was updated to fix the following security issues:

• CVE-2015-8126: Fixed a buffer overflow vulnerabilities in png_get_PLTE/png_set_PLTE functions (bsc#954980).
• CVE-2015-7981: Fixed an out-of-bound read (bsc#952051).

The libpng12 package was updated to fix the following security issues:

• CVE-2015-8126: Fixed a buffer overflow vulnerabilities in png_get_PLTE/png_set_PLTE functions (bsc#954980).
• CVE-2015-7981: Fixed an out-of-bound read (bsc#952051).

This update for java-1_7_1-ibm fixes the following issues by updating to 7.1-3.30 (bsc#963937):

• CVE-2015-5041: Could could have invoked non-public interface methods under certain circumstances
• CVE-2015-7575: The TLS protocol could allow weaker than expected security caused by a collision attack when using the MD5 hash function for signing a ServerKeyExchange message during a TLS handshake. An attacker could exploit this vulnerability using man-in-the-middle techniques to impersonate a TLS server and obtain credentials
• CVE-2015-7981: libpng could allow a remote attacker to obtain sensitive information, caused by an out-of-bounds read in the png_convert_to_rfc1123 function. An attacker could exploit this vulnerability to obtain sensitive information
• CVE-2015-8126: buffer overflow in libpng caused by improper bounds checking by the png_set_PLTE() and png_get_PLTE() functions
• CVE-2015-8472: buffer overflow in libpng caused by improper bounds checking by the png_set_PLTE() and png_get_PLTE() functions
• CVE-2015-8540: libpng is vulnerable to a buffer overflow, caused by a read underflow in png_check_keyword in pngwutil.c. By sending an overly long argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
• CVE-2016-0402: An unspecified vulnerability related to the Networking component has no confidentiality impact, partial integrity impact, and no availability impact
• CVE-2016-0448: An unspecified vulnerability related to the JMX component could allow a remote attacker to obtain sensitive information
• CVE-2016-0466: An unspecified vulnerability related to the JAXP component could allow a remote attacker to cause a denial of service

The png_convert_to_rfc1123 function in png.c in libpng 1.0.x before 1.0.64, 1.2.x before 1.2.54, and 1.4.x before 1.4.17 allows remote attackers to obtain sensitive process memory information via crafted tIME chunk data in an image file, which triggers an out-of-bounds read.

Mikulas Patocka discovered that libpng incorrectly handled certain large fields. If a user or automated system using libpng were tricked into opening a specially crafted image, an attacker could exploit this to cause libpng to crash, leading to a denial of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2012-3425)

Qixue Xiao discovered that libpng incorrectly handled certain time values. If a user or automated system using libpng were tricked into opening a specially crafted image, an attacker could exploit this to cause libpng to crash, leading to a denial of service. (CVE-2015-7981)

It was discovered that libpng incorrectly handled certain small bit-depth values. If a user or automated system using libpng were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or execute code with the privileges of the user invoking the program. (CVE-2015-8126)
