CVE Vulnerability Catalog

Incorrect control of environment variables in PostgreSQL PL/Perl allows an unprivileged database user to change sensitive process environment variables (e.g., PATH). This often suffices for arbitrary code execution, even without a database server OS user account.

A floating-point exception in the PSStack::roll function of Poppler before 25.04.0 can cause application crashes when handling malformed inputs associated with INT_MIN.

The urllib.parse.urlsplit() and urlparse() functions in Python improperly validate bracketed hosts (`[]`), accepting hosts that are not IPv6 or IPvFuture. This violates RFC 3986 and could enable SSRF attacks if a URL is processed by multiple URL parsers.

A medium severity vulnerability in CPython where regular expressions allow excessive backtracking during tarfile.TarFile header parsing, leading to ReDoS via specially crafted tar archives.

A high severity vulnerability in the CPython zipfile module affecting zipfile.Path. When iterating over entry names in a zip archive (e.g., namelist(), iterdir()), unexpected behavior may occur. The more common zipfile.ZipFile class is unaffected.

In CPython, the venv module and CLI do not properly quote paths when creating a virtual environment, allowing injection of commands into activation scripts (e.g., source venv/bin/activate). This enables arbitrary code execution upon activation.

The Diffie-Hellman Key Agreement Protocol allows long exponents, making certain calculations unnecessarily expensive. The 1996 van Oorschot and Wiener paper showed that appropriately short exponents can be used with adequate subgroup constraints, but these are not utilized.

In systemd versions 233 through 259 before 260, an escape-to-host action can occur via a crafted optional config file in nspawn.

A vulnerability in telnet in GNU inetutils through version 2.7 allows servers to read arbitrary environment variables from clients via the NEW_ENVIRON SEND USERVAR command.

A vulnerability in the Linux kernel has been resolved regarding the introduction of locking when enabling/disabling SR-IOV, which led to deadlocks.

In udev in systemd before version 260, local root execution can occur via malicious hardware devices and unsanitized kernel output.

A vulnerability has been identified in the Linux kernel in the rtw_core_enable_beacon() function, which reads 4 bytes from an address that is not a multiple of 4. This can lead to system crashes on some devices.

In OpenPrinting CUPS, versions 2.4.16 and prior, a use-after-free vulnerability exists in the CUPS scheduler (cupsd) when temporary printers are automatically deleted.

telnetd in GNU inetutils through 2.7 allows an out-of-bounds write in the LINEMODE SLC (Set Local Characters) suboption handler because add_slc does not check whether the buffer is full.

A vulnerability in the Linux kernel related to the SDMA block has been fixed, which caused a NULL pointer issue in buffer functions when the SDMA block was not enabled.

W jądrze Linuxa rozwiązano podatność związaną z DML2 w AMD DRM, która mogła prowadzić do błędów walidacji pasma i powodować szare ekrany oraz zawieszanie systemu.

Nieprawidłowa inicjalizacja pamięci cache CPU może umożliwić uprzywilejowanemu atakującemu z dostępem do hypervisora nadpisanie pamięci gościa SEV-SNP, co prowadzi do utraty integralności danych.

W jądrze Linuxa do wersji 6.0.9 odkryto problem związany z warunkiem wyścigu w pliku drivers/media/dvb-core/dvb_frontend.c, który może prowadzić do sytuacji use-after-free w przypadku odłączenia urządzenia.

W jądrze Linuxa do wersji 5.19.12 występuje warunek wyścigu oraz wynikające z tego użycie po zwolnieniu pamięci, gdy atakujący w fizycznej bliskości usunie urządzenie PCMCIA podczas wywoływania ioctl. Problem ten dotyczy wyścigu między funkcjami mgslpc_ioctl a mgslpc_detach.

W jądrze Linuxa przed wersją 5.2.3 odkryto problem związany z użyciem po zwolnieniu pamięci (use-after-free), który jest spowodowany przez złośliwe urządzenie USB w sterowniku drivers/media/usb/dvb-usb/dvb-usb-init.c.
