Hoard before 3.9 may allocate too little memory

CVE-2012-2676 · published 14 years ago
Summary

Multiple integer overflows in the (1) malloc and (2) calloc functions in Hoard before 3.9 make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows on implementing code via a large size value, which causes less memory to be allocated than expected.
