Debian: >> Debian Linux >> 11.0 Security Vulnerabilities
A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible.

A flaw was found in JSS, where it did not properly free up all memory. Over time, the wasted memory builds up in the server memory, saturating the server’s RAM. This flaw allows an attacker to force the invocation of an out-of-memory process, causing a denial of service.

A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash.

libtiff's tiffcrop utility has a uint32_t underflow that can lead to out of bounds read and write. An attacker who supplies a crafted file to tiffcrop (likely via tricking a user to run tiffcrop on it with certain parameters) could cause a crash or in some cases, further exploitation.
