Weekly CVE digest
One email a week with newly published vulnerabilities worth knowing about. No account needed.
This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.
Wykryto podatność w GNU Binutils do wersji 2.43, która dotyczy funkcji disassemble_bytes w pliku binutils/objdump.c. Manipulacja argumentem buf prowadzi do przepełnienia bufora na stosie, co może być wykorzystane do zdalnego ataku.
Wykryto podatność w GNU Binutils 2.45, która dotyczy funkcji dump_dwarf_section w pliku binutils/objdump.c. Manipulacja tą funkcją prowadzi do odczytu poza przydzielonym zakresem pamięci.
W GNU Binutils 2.45 znaleziono lukę w funkcji _bfd_elf_parse_eh_frame w pliku bfd/elf-eh-frame.c komponentu Linker. Wykonanie manipulacji może prowadzić do przepełnienia bufora w pamięci dynamicznej.
An integer overflow in OpenJPEG v2.4.0 allows remote attackers to crash the application, causing a Denial of Service (DoS). This occurs when using the "-ImgDir" command line option on a directory containing 1048576 files.
A heap-based buffer overflow was found in openjpeg in color.c:379:42 in sycc420_to_rgb when decompressing a crafted .j2k file. An attacker could use this to execute arbitrary code with the permissions of the application compiled against openjpeg.
W funkcji alloc_segs w pliku hash.c w bibliotece Mozilla Network Security Services (NSS) występuje przepełnienie bufora oparte na stercie, które może być wykorzystane przez atakujących w zależności od kontekstu przy użyciu spreparowanego pliku cert8.db.
W systemd w wersji 253 odkryto problem, który pozwala atakującemu na skrócenie zablokowanego pliku dziennika, a następnie wznowienie jego blokady w taki sposób, że sprawdzenie integralności nie wykazuje błędów, mimo że plik został zmodyfikowany.
W systemie rPath Linux 1 skrypty inicjalizacyjne ustalają niebezpieczne uprawnienia dla pliku /var/log/btmp, co pozwala lokalnym użytkownikom na uzyskanie wrażliwych informacji dotyczących prób uwierzytelnienia. Dodatkowo, sshd wykrywa te niebezpieczne uprawnienia i nie rejestruje niektórych zdarzeń.
A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input directory with a large number of files. When it fails to allocate a buffer to store the filenames, it calls free() on an uninitialized pointer, leading to a segmentation fault and potential denial of service.
Checking excessively long DSA keys or parameters may be very slow. Applications using EVP_PKEY_param_check() or EVP_PKEY_public_check() to verify DSA public keys or parameters may experience long delays.
A vulnerability was found in PHP where setting the environment variable PHP_CLI_SERVER_WORKERS to a large value leads to a heap buffer overflow.
GNU Midnight Commander 4.8.29-146-g299d9a2fb was found to contain a NULL pointer dereference in the function x_error_handler() at tty/x11conn.c. NOTE: this is disputed because it should be categorized as a usability problem (an X operation silently fails).
A flaw was found in unzip due to improper handling of Unicode strings, leading to a null pointer dereference. An attacker can supply a specially crafted zip file, causing a crash or code execution.
Loofah::HTML5::Scrub.allowed_uri? does not correctly reject javascript: or vbscript: URIs when the scheme is split by a numeric character reference that has no trailing semicolon. A browser decodes such references and resolves the URL to an executable javascript: scheme, while allowed_uri? considers it safe.
REXML is an XML toolkit for Ruby. Versions 3.3.3 to 3.4.1 have a DoS vulnerability when parsing XML containing multiple XML declarations. If you parse untrusted XMLs, you may be impacted. REXML gem 3.4.2 or later includes the patches.
Loofah::HTML5::Scrub.allowed_uri? does not correctly reject javascript: URIs when the scheme is split or prefixed by the HTML5 named character references 	 (tab) or 
 (line feed). This is a bypass of the fix for GHSA-46fp-8f5p-pf2m, which handled the equivalent numeric character references.
A flaw in GnuPG before version 2.2.18 allows certificate signature forgery using SHA-1 collision attacks. An attacker can create forged certificate signatures, compromising authentication integrity.
The CIL compiler in SELinux 3.2 has a use-after-free vulnerability in the __cil_verify_classperms function, called from __cil_verify_classpermission and __cil_pre_verify_helper.
A vulnerability in the OpenSSL library allows unbounded memory growth when processing TLSv1.3 sessions in certain non-default server configurations. An attacker can exploit this to cause a Denial of Service (DoS).
A vulnerability was found in the brace-expansion library up to versions 1.1.11, 2.0.1, 3.0.0, and 4.0.0, involving inefficient regular expression complexity in the expand function in index.js. The attack can be launched remotely.
