A flaw was found in m17n-lib. A partial failure during m17ninit() can leave the internal minputdriver pointer NULL. A subsequent call to minputopenim() can dereference this NULL pointer instead of returning an initialization error, resulting in a crash. No reproducer was supplied for this claim, and attempts to force the specific precondition (an early module-init failure inside m17ninit(), e.g. via a bogus M17NDIR) did not trigger it directly -- the library tolerates a missing or invalid database path gracefully in the tested configuration. Source review of src/m17n.c confirms the claimed code path is real: m17ninit() calls a chain of module initializers (mcharsetinit, mcodinginit, mcharsetloadfromdatabase, mcodingloadfromdatabase, mlanginit, mlocaleinit) and jumps to an err: label on the first failure, which skips the subsequent minputinit() call entirely. minputinit() is the only place the global minputdriver pointer is assigned; it is NULL otherwise. src/input.c:4786 then does driver = minputdriver; and src/input.c:4799 dereferences it unconditionally via im->driver = driver; with no NULL check. The crash is real but requires one of the six earlier module initializers to fail first (e.g. under memory pressure or a corrupted system m17n database), a narrower precondition than the other three issues reported alongside this one. No live reproduction was achieved; this assessment is based on code review alone.

GNU Aspell contains an out-of-bounds read vulnerability in ReadOnlyDict::load() in readonlyws.cpp. When loading a binary .rws dictionary file, it uses offset fields from the file header as byte indices into a heap buffer without validating their bounds. An attacker can trigger this by convincing a user to run aspell with a crafted dictionary file supplied through --master, --dict-dir, or configuration options, leading to heap memory disclosure or a denial of service via application crash.

This issue was fixed in commit 941953b25031bc9104e83f58e138a664b8dedc3f which will be released in version 0.60.8.3.

GNU Aspell prezip-bin contains a heap-based buffer overflow vulnerability in the decompressor in prog/prezip.c. The decompressor does not properly check buffer space, so a crafted compressed file can cause out-of-bounds read and write operations on the heap. An attacker who convinces a user to process a malicious compressed file with prezip-bin can trigger memory corruption, leading to a processs crash.

This issue was fixed in commit 15b188437f9e0192d4ac4472ad66a4e2f62a782f which will be released in version 0.60.8.3.

GNU Aspell contains an integer truncation vulnerability in the WritableDict::add() function in modules/speller/default/writable.cpp. When loading a personal wordlist, the word length is stored as a single byte, causing truncation for words whose length is a multiple of 256. This leads to heap corruption. An attacker can exploit this by convincing a user to run aspell with a crafted personal wordlist containing such a word, resulting in denial of service.

This issue was fixed in commit 782ce94e4dc71eaec4ee1bd945eb3b9c47c5387d which will be released in version 0.60.8.3.

GNU coreutils unexpand is vulnerable to a heap-based buffer overflow due to an integer overflow during buffer allocation when processing large tab stop (-t) values. The multiplication used to calculate the allocation size can wrap around, resulting in an undersized buffer. When processing crafted input, subsequent writes exceed the allocated memory, leading to an out‑of‑bounds heap write.

When running GNU coreutils unexpand with attacker-provided large tab stop (-t) arguments, this behavior leads to a crash and potentially achieve a heap write primitive depending on memory layout.

This issue has been fixed in the commit b60a159fdc5bfcf9988d3a4cb6f53abe8ad5d35d

One-byte overread in strncasecmp on Power8

A security vulnerability has been detected in GNU Binutils 2.47. Affected is the function elfx8664commonsectionindex of the file bfd/elf64-x86-64.c of the component ELF Section Handler. The manipulation leads to null pointer dereference. The attack needs to be performed locally. The exploit has been disclosed publicly and may be used. Upgrading to version 2.48 is able to address this issue. The identifier of the patch is 7322e9bc30cb282575a701c307851fd3d66fee68. It is suggested to upgrade the affected component.

A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.

Calling wordexp with WRDEAPPEND in the GNU C Library version 2.0 to version 2.43 can cause the interface to return invalid memory in the wewordv member, which on subsequent calls to wordfree may abort the process.

glibc2 does not properly clear the LDDEBUGOUTPUT and LDDEBUG environmental variables when a program is spawned from a setuid program, which could allow local users to overwrite files via a symlink attack.

A stack-based buffer overflow in the dynamic loader (ld.so) of the GNU C Library (glibc) versions 2.14 through 2.44 allows a local attacker to crash or corrupt the memory of setuid/setgid (ATSECURE) programs.

When such a program's DTRPATH or DTRUNPATH begins with $ORIGIN and is followed by NUL or '/' the loader both reads past the end of the path buffer and writes past the end of a stack-allocated internal buffer. The corrupted loader stack can lead to a loader crash (denial of service) and limited disclosure of process memory.
