No affected components available
Affected versions of this crate would call Vec::set_len on an uninitialized
vector with user-provided type parameter, in an interface of the HDR image
format decoder. They would then also call other code that could panic before
initializing all instances.
This could run Drop implementations on uninitialized types, equivalent to use-after-free, and allow an attacker arbitrary code execution.
Two different fixes were applied. It is possible to conserve the interface by
ensuring proper initialization before calling Vec::set_len. Drop is no longer
called in case of panic, though.
Starting from version 0.22, a breaking change to the interface requires
callers to pre-allocate the output buffer and pass a mutable slice instead,
avoiding all unsafe code.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
