    Global Buffer Overflow in GNU gzip

    GNU gzip contains a global buffer overflow vulnerability in the LZH decompression logic caused by improper reuse of shared global state between different decompression formats within a single execution. GNU gzip maintains a global array that is shared across the LZ77, LZW, and LZH decompression routines and is not reinitialized between files processed in the same invocation. By decompressing a specially crafted LZW file followed by a specially crafted LZH file in a single gzip -d command, an attacker can poison the shared global state and subsequently trigger an out‑of‑bounds read in the LZH decoder. The LZH decompression logic follows stale

    Predictable Temporary File in GNU gzip

    GNU gzip contains a vulnerability in the gzexe utility related to insecure temporary file handling. When the mktemp utility is not available in the user’s PATH, gzexe falls back to constructing a temporary file path based solely on the process ID (PID). This predictable filename is created without exclusive access or existence checks. A local attacker can pre‑create the predicted temporary file path as a symbolic link pointing to an arbitrary file writable by the victim. When gzexe runs, it follows the symlink and overwrites the target file, resulting in a time‑of‑check to time‑of‑use (TOCTOU) condition that allows arbitrary file overwrite.

  3. CVE-2022-1271

    Hoch · CVSS 8.8EPSS 5,55%Korrektur verfügbar

    CVE-2022-1271

    An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.

    CVE-2010-0001

    Integer underflow in the unlzw function in unlzw.c in gzip before 1.4 on 64-bit platforms, as used in ncompress and probably others, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted archive that uses LZW compression, leading to an array index error.

    Nicht bewertetEPSS 4,18%Korrektur verfügbar

    CVE-2009-2624

    The huft_build function in inflate.c in gzip before 1.3.13 creates a hufts (aka huffman) table that is too small, which allows remote attackers to cause a denial of service (application crash or infinite loop) or possibly execute arbitrary code via a crafted archive. NOTE: this issue is caused by a CVE-2006-4334 regression.

    CVE-2006-4335

    Array index error in the make_table function in unlzh.c in the LZH decompression component in gzip 1.3.5, when running on certain platforms, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted GZIP archive that triggers an out-of-bounds write, aka a "stack modification vulnerability."

    CVE-2005-0988

    Race condition in gzip 1.2.4, 1.3.3, and earlier, when decompressing a gzipped file, allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by gzip after the decompression is complete.

    CVE-2004-0970

    The (1) gzexe, (2) zdiff, and (3) znew scripts in the gzip package, as used by other packages such as ncompress, allows local users to overwrite files via a symlink attack on temporary files. NOTE: the znew vulnerability may overlap CVE-2003-0367.
