Multiple heap-based buffer overflows in the XML manifest encryption tag parsing functionality in OpenOffice.org and LibreOffice before 3.5.5 allow remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted Open Document Text (.odt) file with (1) a child tag within an incorrect parent tag, (2) duplicate tags, or (3) a Base64 ChecksumAttribute whose length is not evenly divisible by four.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

https://cwe.mitre.org/data/definitions/787.html →Open in CWE collection →This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
