Memory Corruption
Memory Corruption is any vulnerability that allows the modification of the content of memory locations in a way not intended by the developer. Memory corruption results are inconsistent; they could lead to fatal errors and system crashes or data leakage; some have no effect at all.
CVE-2013-2429Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 17 and earlier, 6 Update 43 and earlier, and 5.0 Update 41 and earlier; and OpenJDK 6 and 7; allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to ImageIO. NOTE: the previous information is from the April 2013 CPU. Oracle has not commented on claims from another vendor that this issue is related to "JPEGImageWriter state corruption" when using native code, which triggers memory corruption. |
