CVE Vulnerability Catalog

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 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.

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.

The CIL compiler in SELinux 3.2 has a heap-based buffer over-read in ebitmap_match_any, called indirectly from cil_check_neverallow. This occurs due to missing validation of invalid statements in an optional block.

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.

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.

Insufficient checks of the RMP on host buffer access in IOMMU may allow an attacker with privileges and a compromised hypervisor to trigger an out of bounds condition without RMP checks, resulting in a potential loss of confidential guest integrity.

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.

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 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.

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.

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.

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.

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.

The vulnerability involves the ability to set an invalid value for the region input field when calling AWS services using the SDK. An actor with access to the environment where the SDK is used can set an invalid region value.

A certificate with a URI containing an IPv6 address with a zone ID may incorrectly satisfy a URI name constraint in the certificate chain. This vulnerability only affects private PKIs using URIs, as certificates with URIs are not allowed in the public web PKI.

A vulnerability was found in systemd where a service using the DynamicUser property can create a SUID/SGID binary that remains executable with the transient service UID/GID even after the service terminates. A local attacker could exploit this to access resources owned by a potentially different UID/GID.

A vulnerability in the LookPath function causes that when the PATH environment variable contains paths to executable files (rather than just directories), passing certain strings ("", ".", "..") can unexpectedly return binaries listed in PATH.

The vulnerability in the os.OpenFile implementation in Go causes different behavior on Unix and Windows systems when the target path is a dangling symlink. On Unix, the O_EXCL flag prevents following symlinks, while on Windows the function may follow the symlink to a nonexistent location.

A vulnerability in Go's crypto/tls library causes a panic when verifying a certificate chain containing a certificate with an unknown public key algorithm. This affects all TLS clients and servers with client certificate verification enabled.
