- Summary
- [none]
- Details
-
Multiple integer overflows in the (1) GCgenericmalloc and (2) calloc functions in malloc.c, and the (3) GCgenericmallocignoreoff_page function in mallocx.c in Boehm-Demers-Weiser GC (libgc) before 7.2 make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, which causes less memory to be allocated than expected.
