Descriptions
procps-ng before version 3.3.15 is vulnerable to an incorrect integer size in proc/alloc.* leading to truncation/integer overflow issues. This flaw is related to CVE-2018-1124.
procps-ng en versiones anteriores a la 3.3.15 es vulnerable a un tamaño de entero incorrecto en proc/alloc.* que conduce a problemas de truncado/desbordamiento de enteros. Este error está relacionado con CVE-2018-1124.
A flaw was found where procps-ng provides wrappers for standard C allocators that took `unsigned int` instead of `size_t` parameters. On platforms where these differ (such as x86_64), this could cause integer truncation, leading to undersized regions being returned to callers that could then be overflowed. The only known exploitable vector for this issue is CVE-2018-1124.
Qualys performed an extensive audit of procps-ng. They discovered hundreds of bugs and vulnerabilities.
