GHSA-8c6g-4xc5-w96c
No affected components available
Affected versions of Claxon made an invalid assumption about the decode buffer size being a multiple of a value read from the bitstream. This could cause parts of the decode buffer to not be overwritten. If the decode buffer was newly allocated and uninitialized, this uninitialized memory could be exposed.
This allows an attacker to observe parts of the uninitialized memory in the decoded audio stream.
The flaw was corrected by checking that the value read from the bitstream divides the decode buffer size, and returning a format error if it does not. If an error is returned, the decode buffer is not exposed. Regression tests and an additional fuzzer have been added to prevent similar flaws in the future.
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. The attacker needs the user to perform some action, like clicking a link. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
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.
