The function dev_open() in v4l-conf.c does not perform sufficient checks to prevent an unprivileged caller of the program from opening unintended filesystem paths. This allows a local attacker with access to the v4l-conf setuid-root program to test for the existence of arbitrary files and to trigger an open on arbitrary files with mode O_RDWR. To achieve this, relative path components need to be added to the device path, as demonstrated by a v4l-conf -c /dev/../root/.bash_history command." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "url": "https://git.linuxtv.org/xawtv3.git/commit/?id=31f31f9cbaee7be806cba38e0ff5431bd44b20a3", "refsource": "MISC", "name": "https://git.linuxtv.org/xawtv3.git/commit/?id=31f31f9cbaee7be806cba38e0ff5431bd44b20a3" }, { "url": "https://git.linuxtv.org/xawtv3.git/commit/?id=36dc44e68e5886339b4a0fbe3f404fb1a4fd2292", "refsource": "MISC", "name": "https://git.linuxtv.org/xawtv3.git/commit/?id=36dc44e68e5886339b4a0fbe3f404fb1a4fd2292" }, { "url": "https://git.linuxtv.org/xawtv3.git/commit/?id=8e3feea862db68d3ca0886f46cd99fab45d2db7c", "refsource": "MISC", "name": "https://git.linuxtv.org/xawtv3.git/commit/?id=8e3feea862db68d3ca0886f46cd99fab45d2db7c" }, { "url": "https://bugzilla.suse.com/show_bug.cgi?id=CVE-2020-13696", "refsource": "MISC", "name": "https://bugzilla.suse.com/show_bug.cgi?id=CVE-2020-13696" }, { "refsource": "CONFIRM", "name": "http://www.openwall.com/lists/oss-security/2020/06/04/6", "url": "http://www.openwall.com/lists/oss-security/2020/06/04/6" }, { "refsource": "SUSE", "name": "openSUSE-SU-2020:0784", "url": "http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00009.html" }, { "refsource": "SUSE", "name": "openSUSE-SU-2020:0787", "url": "http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00013.html" }, { "refsource": "MLIST", "name": "[debian-lts-announce] 20200612 [SECURITY] [DLA 2246-1] xawtv security update", "url": "https://lists.debian.org/debian-lts-announce/2020/06/msg00018.html" } ] } }
