VCID-7c35-78dy-a7cy
Aliases: CVE-2019-11068 GHSA-qxcg-xjjg-66mj |
Nokogiri gem, via libxslt, is affected by improper access control vulnerability Nokogiri v1.10.3 has been released. This is a security release. It addresses a CVE in upstream libxslt rated as "Priority: medium" by Canonical, and "NVD Severity: high" by Debian. More details are available below. If you're using your distro's system libraries, rather than Nokogiri's vendored libraries, there's no security need to upgrade at this time, though you may want to check with your distro whether they've patched this (Canonical has patched Ubuntu packages). Note that this patch is not yet (as of 2019-04-22) in an upstream release of libxslt. Full details about the security update are available in Github Issue [#1892] https://github.com/sparklemotion/nokogiri/issues/1892. --- CVE-2019-11068 Permalinks are: - Canonical: https://people.canonical.com/~ubuntu-security/cve/CVE-2019-11068 - Debian: https://security-tracker.debian.org/tracker/CVE-2019-11068 Description: > libxslt through 1.1.33 allows bypass of a protection mechanism > because callers of xsltCheckRead and xsltCheckWrite permit access > even upon receiving a -1 error code. xsltCheckRead can return -1 for > a crafted URL that is not actually invalid and is subsequently > loaded. Canonical rates this as "Priority: Medium". Debian rates this as "NVD Severity: High (attack range: remote)". |

libxslt Type Confusion vulnerability that affects Nokogiri In `numbers.c` in libxslt 1.1.33, a type holding grouping characters of an `xsl:number` instruction was too narrow and an invalid character/length combination could be passed to `xsltNumberFormatDecimal`, leading to a read of uninitialized stack data. Nokogiri prior to version 1.10.5 used a vulnerable version of libxslt. Nokogiri 1.10.5 updated libxslt to version 1.1.34 to address this and other vulnerabilities in libxslt. |

Nokogiri implementation of libxslt vulnerable to heap corruption Type confusion in `xsltNumberFormatGetMultipleLevel` prior to libxslt 1.1.33 could allow attackers to potentially exploit heap corruption via crafted XML data. Nokogiri prior to version 1.10.5 contains a vulnerable version of libxslt. Nokogiri version 1.10.5 upgrades the dependency to libxslt 1.1.34, which contains a patch for this issue. |

Update packaged libxml2 (2.9.12 → 2.9.13) and libxslt (1.1.34 → 1.1.35) ## Summary Nokogiri v1.13.2 upgrades two of its packaged dependencies: * vendored libxml2 from v2.9.12 to v2.9.13 * vendored libxslt from v1.1.34 to v1.1.35 Those library versions address the following upstream CVEs: * libxslt: CVE-2021-30560 (CVSS 8.8, High severity) * libxml2: CVE-2022-23308 (Unspecified severity, see more information below) Those library versions also address numerous other issues including performance improvements, regression fixes, and bug fixes, as well as memory leaks and other use-after-free issues that were not assigned CVEs. Please note that this advisory only applies to the CRuby implementation of Nokogiri < 1.13.2, and only if the packaged libraries are being used. If you've overridden defaults at installation time to use system libraries instead of packaged libraries, you should instead pay attention to your distro's `libxml2` and `libxslt` release announcements. ## Mitigation Upgrade to Nokogiri >= 1.13.2. Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link an older version Nokogiri against external libraries libxml2 >= 2.9.13 and libxslt >= 1.1.35, which will also address these same CVEs. ## Impact * libxslt CVE-2021-30560 * CVSS3 score: 8.8 (High) Fixed by https://gitlab.gnome.org/GNOME/libxslt/-/commit/50f9c9c All versions of libxslt prior to v1.1.35 are affected. Applications using untrusted XSL stylesheets to transform XML are vulnerable to a denial-of-service attack and should be upgraded immediately. libxml2 CVE-2022-23308 * As of the time this security advisory was published, there is no officially published information available about this CVE's severity. The above NIST link does not yet have a published record, and the libxml2 maintainer has declined to provide a severity score. * Fixed by https://gitlab.gnome.org/GNOME/libxml2/-/commit/652dd12 * Further explanation is at https://mail.gnome.org/archives/xml/2022-February/msg00015.html The upstream commit and the explanation linked above indicate that an application may be vulnerable to a denial of service, memory disclosure, or code execution if it parses an untrusted document with parse options `DTDVALID` set to true, and `NOENT` set to false. An analysis of these parse options: * While `NOENT` is off by default for Document, DocumentFragment, Reader, and Schema parsing, it is on by default for XSLT (stylesheet) parsing in Nokogiri v1.12.0 and later. * `DTDVALID` is an option that Nokogiri does not set for any operations, and so this CVE applies only to applications setting this option explicitly. It seems reasonable to assume that any application explicitly setting the parse option `DTDVALID` when parsing untrusted documents is vulnerable and should be upgraded immediately. |

Nokogiri gem, via libxslt, is affected by multiple vulnerabilities Nokogiri v1.10.5 has been released. This is a security release. It addresses three CVEs in upstream libxml2, for which details are below. If you're using your distro's system libraries, rather than Nokogiri's vendored libraries, there's no security need to upgrade at this time, though you may want to check with your distro whether they've patched this (Canonical has patched Ubuntu packages). Note that libxslt 1.1.34 addresses these vulnerabilities. Full details about the security update are available in Github Issue [#1943] https://github.com/sparklemotion/nokogiri/issues/1943. --- CVE-2019-13117 https://people.canonical.com/~ubuntu-security/cve/2019/CVE-2019-13117.html Priority: Low Description: In numbers.c in libxslt 1.1.33, an xsl:number with certain format strings could lead to a uninitialized read in xsltNumberFormatInsertNumbers. This could allow an attacker to discern whether a byte on the stack contains the characters A, a, I, i, or 0, or any other character. Patched with commit https://gitlab.gnome.org/GNOME/libxslt/commit/c5eb6cf3aba0af048596106ed839b4ae17ecbcb1 --- CVE-2019-13118 https://people.canonical.com/~ubuntu-security/cve/2019/CVE-2019-13118.html Priority: Low Description: In numbers.c in libxslt 1.1.33, a type holding grouping characters of an xsl:number instruction was too narrow and an invalid character/length combination could be passed to xsltNumberFormatDecimal, leading to a read of uninitialized stack data Patched with commit https://gitlab.gnome.org/GNOME/libxslt/commit/6ce8de69330783977dd14f6569419489875fb71b --- CVE-2019-18197 https://people.canonical.com/~ubuntu-security/cve/2019/CVE-2019-18197.html Priority: Medium Description: In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.
