CVE-2012-3480: GNU Glibc

Medium severity, CVSS 4.6. EPSS: 1% chance of exploitation in the next 30 days.

Multiple integer overflows in the (1) strtod, (2) strtof, (3) strtold, (4) strtod_l, and other unspecified "related functions" in stdlib in GNU C Library (aka glibc or libc6) 2.16 allow local users to cause a denial of service (application crash) and possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow.

Affected products
