Debian Dpkg

dpkg-source in dpkg 1.3.0 through 1.18.23 is able to use a non-GNU patch program and does not offer a protection mechanism for blank-indented diff hunks, which allows remote attackers to conduct directory traversal attacks via a crafted Debian source package, as demonstrated by use of dpkg-source on NetBSD.

dpkg-deb: Fix cleanup for control member with restricted directories

Off-by-one error in the extracthalf function in dpkg-deb/extract.c in the dpkg-deb component in Debian dpkg 1.16.x before 1.16.17 and 1.17.x before 1.17.26 allows remote attackers to execute arbitrary code via the archive magic version number in an "old-style" Debian binary package, which triggers a stack-based buffer overflow.

It was discovered that dpkg-deb (a component of dpkg, the Debian package management system) does not properly validate the end of the data stream when uncompressing a zstd-compressed .deb archive, which may result in denial of service (infinite loop spinning the CPU).

dpkg 1.9.21 does not properly reset the metadata of a file during replacement of the file in a package upgrade, which might allow local users to gain privileges by creating a hard link to a vulnerable (1) setuid file, (2) setgid file, or (3) device, a related issue to CVE-2010-2059.

dpkg 1.15.9 on Debian squeeze introduces support for the "C-style encoded filenames" feature without recognizing that the squeeze patch program lacks this feature, which triggers an interaction error that allows remote attackers to conduct directory traversal attacks and modify files outside of the intended directories via a crafted source package. NOTE: this can be considered a release engineering problem in the effort to fix CVE-2014-0471.

Multiple format string vulnerabilities in the parse_error_msg function in parsehelp.c in dpkg before 1.17.22 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in the (1) package or (2) architecture name.

Directory traversal vulnerability in dpkg-source in dpkg before 1.14.31 and 1.15.x allows user-assisted remote attackers to modify arbitrary files via directory traversal sequences in a patch for a source-format 3.0 package.

dpkg-source in dpkg before 1.14.31 and 1.15.x allows user-assisted remote attackers to modify arbitrary files via a symlink attack on unspecified files in the .pc directory.

dpkg 1.15.9, 1.16.x before 1.16.14, and 1.17.x before 1.17.9 expect the patch program to be compliant with a need for the "C-style encoded filenames" feature, but is supported in environments with noncompliant patch programs, which triggers an interaction error that allows remote attackers to conduct directory traversal attacks and modify files outside of the intended directories via a crafted source package. NOTE: this vulnerability exists because of reliance on unrealistic constraints on the behavior of an external program.

Directory traversal vulnerability in the dpkg-source component in dpkg before 1.14.29 allows remote attackers to modify arbitrary files via a crafted Debian source archive.

Directory traversal vulnerability in the unpacking functionality in dpkg before 1.15.9, 1.16.x before 1.16.13, and 1.17.x before 1.17.8 allows remote attackers to write arbitrary files via a crafted source package, related to "C-style filename quoting."

The dpkg-source command in Debian dpkg before 1.16.16 and 1.17.x before 1.17.25 allows remote attackers to bypass signature verification via a crafted Debian source control file (.dsc).
