Affected: AlmaLinux:8: gzip

The gzip packages contain the gzip (GNU zip) data compression utility. gzip is used to compress regular files. It replaces them with files containing the .gz extension, while retaining ownership modes, access, and modification times.

Security Fix(es):

* gzip: arbitrary-file-write vulnerability (CVE-2022-1271)

Affected: CleanStart: xz

Security vulnerability affects the xz package. An arbitrary file write vulnerability was found in GNU gzip's zgrep utility.

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.

expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE. shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees run-mailcap in the Debian mime-support package before 3.52-1+deb7u1 allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a filename. In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9 Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start o…

Affected: openEuler:20.03-LTS-SP1: gzip, openEuler:20.03-LTS-SP3: gzip, openEuler:22.03-LTS: gzip

gzip is a single-file/stream lossless data compression utility, where the resulting compressed file generally has the suffix .gz. Security Fix(es): The vulnerability exists due to insufficient validation when handling filenames with two or more newlines. A remote attacker can force zgrep or xzgrep to write arbitrary files on the system. The vulnerability allows a remote attacker to compromise an affected system.(CVE-2022-1271)
