CVE Vulnerability Catalog

A vulnerability in the DNS protocol, related to the Closest Encloser Proof aspect in RFC 5155 (when RFC 9276 guidance is skipped), allows remote attackers to cause a denial of service (DoS) by triggering excessive CPU consumption for SHA-1 computations. The attack involves sending DNSSEC responses in a random subdomain attack, known as the NSEC3 issue.

A divide-by-zero error was discovered in py-lmdb 0.97 in the mdb_env_open2 function when mdb_env_read_header obtains a zero value for a certain size field. This issue can be triggered by supplying a crafted data.mdb file.

A vulnerability in Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The multiprocessing library with the forkserver start method permits pickle deserialization from any user on the same local network of the machine.

The email module in Python through 3.11.3 incorrectly parses email addresses containing special characters. The wrong portion of an RFC2822 header is identified as the value of the addr-spec.

In the cryptography package for Python before version 3.3.2, sequences of update calls for symmetric encryption of multi-GB data can cause integer overflow and buffer overflow, as demonstrated with the Fernet class.

A vulnerability in libfuse versions 3.18.0 through 3.18.1 causes a NULL pointer dereference and memory leak in the fuse_uring_init_queue function. A local user can exploit this to crash the FUSE daemon or exhaust system resources.

A vulnerability in systemd causes systemd-coredump to ignore the kernel's fs.suid_dumpable setting, potentially leading to a local information leak.

CPAN.pm before version 2.35 does not verify TLS certificates when downloading distributions over HTTPS. This allows man-in-the-middle attackers to replace downloaded packages with malicious ones.

The pip package before version 19.2 for Python is vulnerable to directory traversal when a URL is provided in an install command. An attacker can exploit a Content-Disposition header containing '../' in the filename to overwrite files, such as /root/.ssh/authorized_keys.

A flaw in shadow-utils fails to properly clear the buffer when a new password is entered twice and the second attempt fails. This leaves the first password in memory, potentially allowing an attacker with sufficient access to retrieve it.

Słaby algorytm szyfrowania w Easy-RSA w wersjach od 3.0.5 do 3.1.7 umożliwia lokalnemu atakującemu łatwiejsze złamanie prywatnego klucza CA, gdy został on utworzony przy użyciu OpenSSL 3.

Shell command injection is possible in Net::SSH::Proxy::Command and Net::SSH::Proxy::Jump. When an application configures a proxy and passes attacker-influenced host, port, or remote_user values to Net::SSH.start (or a jump string to Proxy::Jump.new), shell metacharacters in those values may be interpreted.

Net::SSH::Transport::Session#poll_message pushes every packet received during key exchange that is not on the "allowed during KEX" list into an unbounded @queue (Array) with no size cap. A malicious server that completes KEXINIT (putting net-ssh into pending KEX) and then floods non-allowed packets can cause unbounded memory growth.

Buildx is a Docker CLI plugin that extends build capabilities using BuildKit. Cache backends support credentials by setting secrets directly as attribute values in cache-to/cache-from configuration. When supplied as user input, these secure values may be inadvertently captured in OpenTelemetry traces.

When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache entry, making it end sooner or later than otherwise intended. This affects applications using HSTS and URLs with the insecure HTTP:// scheme.

In GNU patch through version 2.7.6, there is a double free vulnerability in the another_hunk function in pch.c, which can cause a denial of service via a crafted patch file. This issue exists because of an incomplete fix for CVE-2018-6952.

Unclear documentation of error behavior in `ParseWithClaims` in golang-jwt can lead to users not checking errors properly. Especially, if a token is both expired and invalid, the returned errors may be misleading.

Due to a mistake in libcurl's WebSocket code, a malicious server can send a particularly crafted packet which makes libcurl get trapped in an endless busy-loop. There is no other way for the application to escape or exit this loop other than killing the thread/process. This might be used to DoS.

libcurl's ASN1 parser has this utf8asn1str() function used for parsing an ASN.1 UTF-8 string. It can detect an invalid field and return error. Unfortunately, when doing so it also invokes `free()` on a 4 byte local stack buffer. Most modern malloc implementations detect this error and immediately abort.

runc 1.1.13 and earlier, as well as 1.2.0-rc2 and earlier, can be tricked into creating empty files or directories in arbitrary locations in the host filesystem by sharing a volume between two containers and exploiting certain operations.
