Package: apt Version: 1.2.7 Severity: normal The /usr/bin/apt command causes a segmentation fault by list/search/show if the user running it does not have the necessary permissions to read the sources.list files. The bug can be reproduced in the following way:
# ls -l /etc/apt/sources.list.d/ total 4 -rw-r--r-- 1 root root 343 Jan 21 11:33 all.sources # chmod 0640 /etc/apt/sources.list.d/all.sources # ls -l /etc/apt/sources.list.d/ total 4 -rw-r----- 1 root root 343 Jan 21 11:33 all.sources Then as a normal non root user: $ apt search linux-image-amd64 Segmentation fault $ apt show linux-image-amd64 Segmentation fault $ While in that same setting the apt-cache command is able to display an error message with no segfault. $ apt-cache search linux-image-amd64 E: Could not open file /etc/apt/sources.list.d/all.sources - open (13: Permission denied) E: Malformed stanza 1 in source list /etc/apt/sources.list.d/all.sources (type) E: The list of sources could not be read. W: You may want to run apt-get update to correct these problems E: The package cache file is corrupted $ Thanks for working on apt, best regards. -- Package-specific info: -- apt-config dump -- APT ""; APT::Architecture "amd64"; APT::Build-Essential ""; APT::Build-Essential:: "build-essential"; APT::Install-Recommends "1"; APT::Install-Suggests "0"; APT::Sandbox ""; APT::Sandbox::User "_apt"; APT::Authentication ""; APT::Authentication::TrustCDROM "true"; APT::NeverAutoRemove ""; APT::NeverAutoRemove:: "^firmware-linux.*"; APT::NeverAutoRemove:: "^linux-firmware$"; APT::NeverAutoRemove:: "^linux-image-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-headers-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-image-extra-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-signed-image-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-image-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-headers-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^gnumach-image-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^.*-modules-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^.*-kernel-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-backports-modules-.*-4\.3\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-tools-4\.3\.0-1-amd64$"; APT::VersionedKernelPackages ""; APT::VersionedKernelPackages:: "linux-image"; APT::VersionedKernelPackages:: "linux-headers"; APT::VersionedKernelPackages:: "linux-image-extra"; APT::VersionedKernelPackages:: "linux-signed-image"; APT::VersionedKernelPackages:: "kfreebsd-image"; APT::VersionedKernelPackages:: "kfreebsd-headers"; APT::VersionedKernelPackages:: "gnumach-image"; APT::VersionedKernelPackages:: ".*-modules"; APT::VersionedKernelPackages:: ".*-kernel"; APT::VersionedKernelPackages:: "linux-backports-modules-.*"; APT::VersionedKernelPackages:: "linux-tools"; APT::Never-MarkAuto-Sections ""; APT::Never-MarkAuto-Sections:: "metapackages"; APT::Never-MarkAuto-Sections:: "contrib/metapackages"; APT::Never-MarkAuto-Sections:: "non-free/metapackages"; APT::Never-MarkAuto-Sections:: "restricted/metapackages"; APT::Never-MarkAuto-Sections:: "universe/metapackages"; APT::Never-MarkAuto-Sections:: "multiverse/metapackages"; APT::Move-Autobit-Sections ""; APT::Move-Autobit-Sections:: "oldlibs"; APT::Move-Autobit-Sections:: "contrib/oldlibs"; APT::Move-Autobit-Sections:: "non-free/oldlibs"; APT::Move-Autobit-Sections:: "restricted/oldlibs"; APT::Move-Autobit-Sections:: "universe/oldlibs"; APT::Move-Autobit-Sections:: "multiverse/oldlibs"; APT::Keep-Downloaded-Packages "true"; APT::Update ""; APT::Update::Post-Invoke-Success ""; APT::Update::Post-Invoke-Success:: "test -x /usr/bin/apt-show-versions || exit 0 ; apt-show-versions -i"; APT::Update::Post-Invoke ""; APT::Update::Post-Invoke:: "[ ! -x /usr/bin/debtags ] || debtags update || true"; APT::Architectures ""; APT::Architectures:: "amd64"; APT::Compressor ""; APT::Compressor::.
