CVE Vulnerability Catalog

GNU libidn2 before version 2.2.0 fails to perform the roundtrip checks specified in RFC3490 Section 4.2 when converting A-labels to U-labels, allowing domain impersonation in some circumstances. An attacker can create a malicious domain that matches a target domain except for certain characters.

The vulnerability in python-cryptography 3.2 allows Bleichenbacher timing attacks on the RSA decryption API. Attackers can exploit timing differences in processing valid PKCS#1 v1.5 ciphertext.

A buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to cause temporary denial of service on platforms where a 1-byte over-read leads to process termination. This affects the database server and libpq.

The urllib.parse.urlsplit() and urlparse() functions in Python improperly validate bracketed hosts (`[]`), accepting hosts that are not IPv6 or IPvFuture. This violates RFC 3986 and could enable SSRF attacks if a URL is processed by multiple URL parsers.

The libpcre library in PCRE before version 8.44 is vulnerable to an integer overflow. The issue occurs when a large number is used after the (?C substring in a regular expression.

A medium severity vulnerability in CPython where regular expressions allow excessive backtracking during tarfile.TarFile header parsing, leading to ReDoS via specially crafted tar archives.

The CIL compiler in SELinux 3.2 has a use-after-free vulnerability in the cil_reset_classpermission function, called from cil_reset_classperms_set and cil_reset_classperms_list. This could lead to unexpected behavior or potential exploitation by an attacker.

In GraphQL-Ruby before version 2.6.6, when using Execution::Next, authorization failures did not properly halt execution for fields using GraphQL::Schema::Resolver and its subclasses (including Mutation, RelayClassicMutation, and Subscription).

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.

The vulnerability in the Crass library causes unbounded processing of scientific notation in CSS values before clamping the result to Float::MAX. An attacker can send a small crafted CSS string that forces excessive CPU and memory consumption.

The CIL compiler in SELinux 3.2 has a use-after-free vulnerability in the __cil_verify_classperms function, called from __verify_map_perm_classperms and hashtab_map. This could lead to unexpected behavior or potential exploitation by an attacker.

LZ4 before version 1.9.2 has a heap-based buffer overflow in LZ4_write32 (related to LZ4_compress_destSize), affecting applications that call LZ4_compress_fast with large input. This issue can also lead to data corruption.

The vulnerability in the Nokogiri library affects the protected copy helper used by Node#dup and #clone methods. It unwrapped the source argument as an xmlNode without a type check, causing an out-of-bounds read on xmlNs structure and process crash when a non-Node object (e.g. Namespace) was supplied. Version 1.19.4 adds a type check and raises TypeError.

Clients using RFC7250 Raw Public Keys (RPKs) to authenticate a server may fail to notice that the server was not authenticated, because handshakes don't abort as expected when the SSL_VERIFY_PEER verification mode is set. Impact: TLS and DTLS connections using raw public keys...

An issue in Axios 1.5.1 inadvertently reveals the confidential XSRF-TOKEN stored in cookies by including it in the HTTP header X-XSRF-TOKEN for every request made to any host, allowing attackers to view sensitive information.

When curl is told to use the Certificate Status Request TLS extension (OCSP stapling) to verify the server certificate, it might fail to detect some OCSP problems and wrongly consider the response as fine if the returned status reports another error than expected.

runc is a CLI tool for spawning and running containers according to the OCI specification. In versions 1.2.7 and below, 1.3.0-rc.1 through 1.3.1, 1.4.0-rc.1 and 1.4.0-rc.2, runc would not perform sufficient verification that the source of the bind-mount (i.e., the container's /dev/null) was actually...

When Git asks for credentials via a terminal prompt (without using a credential helper), it prints the host name for which the credentials are requested. This may lead to unintended disclosure of the host name.

A vulnerability in the Crass library causes excessive CPU consumption when parsing input containing non-ASCII characters. Inefficient tracking of multi-byte character positions leads to superlinear parsing time.

A vulnerability in the Crass library allows a DoS attack by providing a stylesheet with a very large number of adjacent CSS comments when the :preserve_comments option is disabled (default behavior). This causes excessive recursion and potential system resource exhaustion.
