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-2026-48982: Concurrent Execution using Shared Resource with Improper Synchronization

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, when updating a one-time pad file, a temporary file is created using open without the OEXCL flag. Without OEXCL, the create operation is not atomic: two concurrent processes racing to...

ALPINE-CVE-2025-0913

os.OpenFilepath, os.OCREATE|OEXCL behaved differently on Unix and Windows systems when the target path was a dangling symlink. On Unix systems, OpenFile with OCREATE and OEXCL flags never follows symlinks. On Windows, when the target path was a symlink to a nonexistent location, OpenFile would...

os.OpenFilepath, os.OCREATE|OEXCL behaved differently on Unix and Windows systems when the target path was a dangling symlink. On Unix systems, OpenFile with OCREATE and OEXCL flags never follows symlinks. On Windows, when the target path was a symlink to a nonexistent location, OpenFile would...

CVE-2025-0913

The Go programming language's os.OpenFile(path, os.O_CREATE|O_EXCL) function exhibited inconsistent behavior when handling dangling symlinks across different operating systems. On Unix systems, the function correctly ignored symlinks, but on Windows, it would create a file in the location pointed...

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...
