expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE. shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees run-mailcap in the Debian mime-support package before 3.52-1+deb7u1 allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a filename. In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9 Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start o…

Elfutils is a collection of utilities, including stack (to show backtraces), nm (for listing symbols from object files), size (for listing the section sizes of an object or archive file), strip (for discarding symbols), elflint (to check for well-formed ELF files) and elfcompress (to compress or decompress ELF sections). Also included are helper libraries which implement DWARF, ELF, and machine-specific ELF handling and process introspection. It also provides a DSO which allows reading and writing ELF files on a high level. Third party programs depend on this package to read internals of ELF files. Yama sysctl setting to enable default attach scope settings enabling programs to use ptrace attach, access to /proc/PID/{mem,personality,stack,syscall}, and the syscalls process_vm_readv and process_vm_writev which are used for interprocess services, communication and introspection (like synchronisation, signaling, debugging, tracing and profiling) of processes.
