| CVE-2026-41992 | ALTO7.5 | 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 rein | 29/06/2026 |
| CVE-2026-41991 | MEDIO4.7 | 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 e | 29/06/2026 |
| CVE-2022-1271 | ALTO8.8 | 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 filen | 31/08/2022 |
| CVE-2010-0001 | MEDIO6.8 | 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 erro | 29/01/2010 |
| CVE-2009-2624 | MEDIO6.8 | 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 regre | 29/01/2010 |
| CVE-2005-0758 | MEDIO4.6 | zgrep in gzip before 1.3.5 does not properly sanitize arguments, which allows local users to execute arbitrary commands via filenames that are injected into a sed script. | 13/05/2005 |
| CVE-2005-1228 | MEDIO5.0 | Directory traversal vulnerability in gunzip -N in gzip 1.2.4 through 1.3.5 allows remote attackers to write to arbitrary directories via a .. (dot dot) in the original filename within a compressed file. | 02/05/2005 |
| CVE-2005-0988 | BAJO3.7 | 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. | 02/05/2005 |
| CVE-2004-0970 | BAJO2.1 | 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. | 09/02/2005 |
| CVE-2004-0603 | CRÍTICO10.0 | gzexe in gzip 1.3.3 and earlier will execute an argument when the creation of a temp file fails instead of exiting the program, which could allow remote attackers or local users to execute arbitrary commands, a different vulnerability than CVE-1999-1332. | 06/12/2004 |
| CVE-2004-1349 | BAJO2.1 | gzip before 1.3 in Solaris 8, when called with the -f or -force flags, will change the permissions of files that are hard linked to the target files, which allows local users to view or modify these files. | 04/10/2004 |
| CVE-2003-0367 | BAJO2.1 | znew in the gzip package allows local users to overwrite arbitrary files via a symlink attack on temporary files. | 02/07/2003 |
| CVE-2001-1228 | ALTO7.5 | Buffer overflows in gzip 1.3x, 1.2.4, and other versions might allow attackers to execute code via a long file name, possibly remotely if gzip is run on an FTP server. | 18/11/2001 |
