CVE-2006-7252: Freebsd

Medium severity, CVSS 5.0. EPSS: 1.1% chance of exploitation in the next 30 days.

Integer overflow in the calloc function in libc/stdlib/malloc.c in jemalloc in libc for FreeBSD 6.4 and NetBSD makes it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, which triggers a memory allocation of one byte.

• Freebsd Freebsd: version 6.4 only
• Netbsd Netbsd: any version
