CVE Vulnerability Catalog

A vulnerability in pip prior to version 23.3 allows injecting arbitrary configuration options into the 'hg clone' call when installing a package from a Mercurial VCS URL (hg+...). An attacker can control Mercurial configuration, modifying how and what is cloned.

A vulnerability in the Nokogiri library allows calling `Document#encoding=` with an invalid encoding (e.g., a non-string or a string containing a null byte), which frees the document's current encoding string without replacing it. The document is left referencing freed memory, leading to a use-after-free condition on the next call.

The vulnerability in the Nokogiri library for JRuby causes the NONET option to be incorrectly enforced when parsing XML schemas. This allows an attacker to load external network resources, potentially leading to data leakage or SSRF attacks.

Nokogiri has a bug in methods called on allocated-but-uninitialized native wrapper classes inheriting from `Nokogiri::XML::Node`. This causes a NULL pointer dereference that could crash the process.

The vulnerability in the Nokogiri library causes `Nokogiri::XML::XPathContext` to not keep its source document alive for garbage collection. If an XPathContext outlives its document and the document is collected, evaluating an XPath expression could read invalid memory and potentially segfault.

Nokogiri's CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an XML attribute. If Ruby code had already accessed an attribute child node, `Nokogiri::XML::Attr#value=` could free the underlying native child node while the wrapper remains.

A vulnerability in the Nokogiri library allows a DTD node to be set as the document root, leading to a heap use-after-free during garbage collection or finalization. This results in an invalid memory read or potentially a segfault.

An issue was discovered in shadow 4.5. newgidmap (in shadow-utils) is setuid and allows an unprivileged user to be placed in a user namespace where setgroups(2) is permitted. This allows an attacker to remove themselves from a supplementary group, which may allow access to certain filesystem paths.

The vulnerability in the Nokogiri library affects the `Nokogiri::XML::Node#do_xinclude` method, which during XInclude processing removes `<xi:include>` nodes along with their children (e.g., `<xi:fallback>`) and declared namespaces. If an application previously accessed these nodes, unexpected behavior may occur.

A segmentation fault was discovered in the libde265 library (commit d9fea9d) in the decoder_context::compute_framedrop_table() function. This vulnerability may cause crashes in applications using this library.

A vulnerability in TLS 1.3 with certificate compression can force a large buffer allocation before decompression without checking the configured certificate size limit. An attacker can cause per-connection memory allocations of up to approximately 22 MiB.

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.

If an application using the `SSL_CIPHER_find()` function in a QUIC protocol client or server receives an unknown cipher suite from the peer, a NULL dereference occurs. This leads to abnormal termination of the running process, causing Denial of Service (DoS).

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.

On Red Hat Enterprise Linux systems with xdg-user-dirs before 0.15.5, the system umask policy is not honored when creating XDG user directories because Xsession sources xdg-user-dirs.sh before setting umask. This may lead to incorrect directory permissions.

Improper handling of values in the microcode flow for some Intel(R) Processor Family may allow an escalation of privilege. A privileged user combined with a high complexity attack may enable this via local access.

In FRRouting (FRR) up to version 7.3.1, when using the split-config feature, the init script creates an empty config file with world-readable default permissions, potentially leading to information leakage via frr.in and frrcommon.sh.in tools.

The getlong function in numutils.c in libdoc through 2017-10-23 has a heap-based buffer over-read that allows attackers to cause a denial of service (application crash) via a crafted file.

In libdoc through 2019-01-28, calcFileBlockOffset in ole.c allows division by zero. This can lead to an application crash.

In libdoc through 2019-01-28, doc2text in catdoc.c has a NULL pointer dereference. This can lead to an application crash.
