stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution.

An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27 and earlier may write data beyond the target buffer, leading to a buffer overflow in __mempcpy_avx512_no_vzeroupper.

The DPDK vhost-user interface does not check to verify that all the requested guest physical range is mapped and contiguous when performing Guest Physical Addresses to Host Virtual Addresses translations. This may lead to a malicious guest exposing vhost-user backend process memory. All versions before 18.02.1 are vulnerable.

An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption.

XML external entity (XXE) vulnerability in StaxXMLFactoryProvider2 in Odata4j, as used in Red Hat JBoss Data Virtualization before 6.0.0 patch 4, allows remote attackers to read arbitrary files via a crafted request to a REST endpoint.

Teiid before 8.4.3 and before 8.7 and Red Hat JBoss Data Virtualization 6.0.0 before patch 3 allows remote attackers to read arbitrary files via a crafted request to a REST endpoint, related to an XML External Entity (XXE) issue.
