FreeBSD : mozilla -- 64 bit JIT WASM read on left over memroy (a93a1d2a-109d-11f0-8195-b42e991fc52e)

high Nessus Plugin ID 233851

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

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 a93a1d2a-109d-11f0-8195-b42e991fc52e advisory.

 [email protected] reports:
 On 64-bit CPUs, when the JIT compiles WASM i32 return values they can pick up bits from left over memory.
 This can potentially cause them to be treated as a different type.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
