CVE-2026-65064 Data::HashMap::Shared versions before 0.14 for Perl create a world-readable mmap backing file and open it without O_EXCL or O_NOFOLLOW
Data::HashMap::Shared versions before 0.14 for Perl create a world-readable mmap backing file and open it without OEXCL or ONOFOLLOW. The segment is created in shmgeneric.h with openpath, ORDWR | OCREAT | OCLOEXEC, 0666. The mode is 0666, so under the default umask 022 the file is created mode 06...

GHSA-239G-2685-54X3 install: TOCTOU symlink race (unlink-then-create without O_EXCL) allows arbitrary file overwrite
copyfile in install/src/install.rs removes the destination then recreates it by pathname via File::create / fs::copy without OEXCL/createnew. Between the unlink and the recreate, a local attacker with write access to the destination directory can drop in a symlink and redirect the write. Impact:...

CVE-2025-0913
CVE-2025-0913 : The Go standard library change fixes a mismatch in behavior of os.OpenFile with O_CREATE|O_EXCL when the path is a dangling symlink. Previously Unix vs Windows differed; now the operation returns an error if both flags are set and the target is a symlink. This vulnerability is rat...
NewStart CGSL CORE 5.04 / MAIN 5.04 : libqb Vulnerability (NS-SA-2020-0057)
The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has libqb packages installed that are affected by a vulnerability: - libqb before 1.0.5 allows local users to overwrite arbitrary files via a symlink attack, because it uses predictable filenames under /dev/shm and /tmp without...
Open redirect
On desktop, Ubuntu UI Toolkit's StateSaver would serialise data on tmp/ files which an attacker could use to expose potentially sensitive data. StateSaver would also open files without the OEXCL flag. An attacker could exploit this to launch a symlink attack, though this is partially mitigated by...
