CVE-2012-2674
Multiple integer overflows in the (1) chk_malloc, (2) leak_malloc, and (3) leak_memalign functions in libc/bionic/malloc_debug_leak.c in Bionic (libc) for Android, when libc.debug.malloc is set, make it easier for context-dependent attackers to perform…
Does this matter?
Lower severity and a low EPSS score (0.79%). Track it; it rarely justifies an emergency change on its own.
Description
Multiple integer overflows in the (1) chk_malloc, (2) leak_malloc, and (3) leak_memalign functions in libc/bionic/malloc_debug_leak.c in Bionic (libc) for Android, when libc.debug.malloc is set, 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.
