Siemens SIMATIC S7-1500 Signed to Unsigned Conversion Error (CVE-2020-6096)

An exploitable signed comparison vulnerability exists in the ARMv7 memcpy implementation of GNU glibc 2.30.9000. Calling memcpy on ARMv7 targets that utilize the GNU glibc implementation with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker...

The remote Fedora 32 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-6e581c051a advisory. - The iconv program in the GNU C Library aka glibc or libc6 2.31 and earlier, when invoked with multiple suffixes in the destination encoding...

An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc 2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the 'num' parameter to memcpy() this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data.
