critical: firefox/tar security update
An update for firefox/tar is now available for NewStart CGSL MAIN 4.05.
NewStart Security has rated this update as having a security impact of critical. A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
firefox: Mozilla Firefox is an open-source web browser, designed for standards compliance, performance and portability.
tar: The GNU tar program saves many files together in one archive and can restore individual files (or all of the files) from that archive. Tar can also be used to add supplemental files to an archive and to update or list files in the archive. Tar includes multivolume support, automatic archive compression/decompression, the ability to perform remote archives, and the ability to perform incremental and full backups. If you want to use tar for remote backups, you also need to install the rmt package.
firefox: Incorrect convexity calculations in Skia in Google Chrome prior to 72.0.3626.81 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page.(CVE-2019-5785)
firefox: The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor function is entered through on-stack replacement (OSR). This allows for possible arbitrary reading and writing of objects during an exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.(CVE-2019-9791)
firefox: Incorrect alias information in IonMonkey JIT compiler for Array.prototype.slice method may lead to missing bounds check and a buffer overflow. This vulnerability affects Firefox < 66.0.1, Firefox ESR < 60.6.1, and Thunderbird < 60.6.1.(CVE-2019-9810)
firefox: Incorrect handling of __proto__ mutations may lead to type confusion in IonMonkey JIT code and can be leveraged for arbitrary memory read and write. This vulnerability affects Firefox < 66.0.1, Firefox ESR < 60.6.1, and Thunderbird < 60.6.1.(CVE-2019-9813)
firefox: When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65.(CVE-2018-18506)
firefox: Mozilla developers and community members reported memory safety bugs present in Firefox 65, Firefox ESR 60.5, and Thunderbird 60.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.(CVE-2019-9788)
firefox: A use-after-free vulnerability can occur when the SMIL animation controller incorrectly registers with the refresh driver twice when only a single registration is expected. When a registration is later freed with the removal of the animation controller element, the refresh driver incorrectly leaves a dangling pointer to the driver's observer array. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.(CVE-2019-9796)
firefox: An integer overflow in path handling lead to a use after free in Skia in Google Chrome prior to 71.0.3578.80 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.(CVE-2018-18356)
tar: Buffer overflow in tar 1.14 through 1.15.90 allows user-assisted attackers to cause a denial of service (application crash) and possibly execute code via unspecified vectors involving PAX extended headers.(CVE-2006-0300)
tar: GNU tar 1.16 and 1.15.1, and possibly other versions, allows user-assisted attackers to overwrite arbitrary files via a tar file that contains a GNUTYPE_NAMES record with a symbolic link, which is not properly handled by the extract_archive function in extract.c and extract_mangle function in mangle.c, a variant of CVE-2002-1216.(CVE-2006-6097)
tar: Directory traversal vulnerability in the contains_dot_dot function in src/names.c in GNU tar allows user-assisted remote attackers to overwrite arbitrary files via certain //.. (slash slash dot dot) sequences in directory symlinks in a TAR archive.(CVE-2007-4131)
tar: Buffer overflow in the safer_name_suffix function in GNU tar has unspecified attack vectors and impact, resulting in a "crashing stack."(CVE-2007-4476)
tar: Heap-based buffer overflow in the rmt_read__ function in lib/rtapelib.c in the rmt client functionality in GNU tar before 1.23 and GNU cpio before 2.11 allows remote rmt servers to cause a denial of service (memory corruption) or possibly execute arbitrary code by sending more data than was requested, related to archive filenames that contain a : (colon) character.(CVE-2010-0624)
tar: Directory traversal vulnerability in the safer_name_suffix function in GNU tar 1.14 through 1.29 might allow remote attackers to bypass an intended protection mechanism and write to arbitrary files via vectors related to improper sanitization of the file_name parameter, aka POINTYFEATHER.(CVE-2016-6321)
