AMD. A buffer overflow issue was addressed with improved memory handling.
A use-after-free in Busybox 1.35-x's awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the copyvar function.
A vulnerability was found in curl. This issue occurs because the number of acceptable "links" in the "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps. This flaw leads to a denial of service, either by mistake or by a malicious actor.
A malicious server can serve excessive amounts of Set-Cookie: headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on foo.example.com can set cookies that also would match for bar.example.com, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method.
Affected devices use a weak encryption scheme to encrypt the debug zip file. This could allow an authenticated attacker to decrypt the contents of the file and retrieve debug information about the system.
Affected devices store the CLI user passwords encrypted in flash memory. Attackers with physical access to the device could retrieve the file and decrypt the CLI user passwords.
Affected devices do not check the TFTP blocksize correctly. This could allow an authenticated attacker to read from an uninitialized buffer that potentially contains previously allocated data.
