FreeBSD -- Heap overflow in libnv

Problem Description: When processing the header of an incoming message, libnv failed to properly validate the message size. Impact: The lack of validation allows a malicious program to write outside the bounds of a heap allocation. This can trigger a crash or system panic, and it may be possible...

The vulnerability of the libnv library in FreeBSD systems allows attackers to increase their privileges or cause service failures.

The vulnerability of the libnv library in FreeBSD systems is related to a potential overflow due to incorrect calculations of buffer size. Exploiting this vulnerability can allow an attacker to increase their privileges or cause service interruptions...

FreeBSD : FreeBSD -- Integer overflow in libnv (93c12fe5-7716-11ef-9a62-002590c1f29c)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 93c12fe5-7716-11ef-9a62-002590c1f29c advisory. A malicious value of size in a structure of packed libnv can cause an integer overflow, leading to the...

FreeBSD -- Integer overflow in libnv

Problem Description: A malicious value of size in a structure of packed libnv can cause an integer overflow, leading to the allocation of a smaller buffer than required for the parsed data. The introduced check was incorrect, as it took into account the size of the pointer, not the structure. Thi...
