DEBIAN-CVE-2026-19023

Untrusted pointer dereference in the renderbinoutput function in the h5dump tool in HDF5 before 2.3.0 allows attackers to cause a denial of service via a variable-length string dataset with more than one element dumped in binary mode, which corrupts the per-element stride calculation and causes...

CVE-2026-64569

In CVE-2026-64569, on Linux kernel builds with CONFIG_INET=n, mpls_valid_fib_dump_req() dereferences NULL when handling RTM_GETROUTE dumps for AF_MPLS because tb[RTA_OIF] is passed to nla_get_u32() without checking presence, and the path bypasses ip_valid_fib_dump_req(). This can allow an unprivi...

Security Bulletin:UltraJSON Memory Leak Fix in ujson.dump() Prior to 5.12.1

Summary UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Prior to 5.12.1, when ujson.dump writes to a file-like object and the write operation raises an exception, the serialized JSON string object is not decremented, leaking memory. Each failed write...

postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...

abrt: ChownProblemDir succeeds during active post-create event processing due to inadequate locking

A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DDOPENREADONLY and calls ddchown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows ...
