Background ========= VLC is a cross-platform media player and streaming server. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-video/vlc < 3.0.10 > = 3.0.10 Description ========== A buffer overflow in DecodeBlock in sdl_image.c was discovered. Impact ===== A remote user could craft a specifically crafted image file that could execute arbitrary code or cause denial of service. Workaround ========= The user should refrain from opening files from untrusted third parties or accessing untrusted remote sites (or disable the VLC browser plugins), until they upgrade. Resolution ========= All VLC users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =media-video/vlc-3.0.10" References ========= [ 1 ] CVE-2019-19721 https://nvd.nist.gov/vuln/detail/CVE-2019-19721 [ 2 ] Upstream patch ;a=commit;h=72afe7ebd8305bf4f5360293b8621cde52ec506b [ 3 ] VideoLAN-SB-VLC-309 https://www.videolan.org/security/sb-vlc309.html Availability =========== This GLSA and any updates to it areavailable for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202005-11 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.

A vulnerability in LibYAML could allow an attacker to execute arbitrary code or cause a Denial of Service condition.. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201405-27 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: LibYAML: Arbitrary code execution Date: May 23, 2014 Bugs: #505948 ID: 201405-27 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= A vulnerability in LibYAML could allow an attacker to execute arbitrary code or cause a Denial of Service condition. Background ========= LibYAML is a YAML 1.1 parser and emitter written in C. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libyaml < 0.1.6 > = 0.1.6 Description ========== The yaml_parser_scan_uri_escapes() function does not properly expand strings passed as input, which can result in a heap-based buffer overflow. Impact ===== An attacker could provide a specially-crafted YAML document, which, when parsed by LibYAML, could result in arbitrary code execution or cause the application to crash. Workaround ========= There is no known workaround at this time. Resolution ========= All LibYAML users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =dev-libs/libyaml-0.1.6" Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages.
