UnknownEPSS 2.61%

Last modified

CVE-2013-4332 is a vulnerability of currently unknown severity. Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5) aligned_alloc functions.. EPSS estimates a 2.61% chance of exploitation in the next 30 days.
