{"id":"MGASA-2019-0313","summary":"Updated libxslt packages fix security vulnerabilities","details":"Updated libxslt package fixes security vulnerabilities:\n\n* In numbers.c in libxslt 1.1.33, an xsl:number with certain format strings\n  could lead to a uninitialized read in xsltNumberFormatInsertNumbers. This\n  could allow an attacker to discern whether a byte on the stack contains\n  the characters A, a, I, i, or 0, or any other character (CVE-2019-13117).\n\n* In numbers.c in libxslt 1.1.33, a type holding grouping characters of an\n  xsl:number instruction was too narrow and an invalid character/length\n  combination could be passed to xsltNumberFormatDecimal, leading to a read\n  of uninitialized stack data (CVE-2019-13118).\n\n* In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't\n  reset under certain circumstances. If the relevant memory area happened to\n  be freed and reused in a certain way, a bounds check could fail and memory\n  outside a buffer could be written to, or uninitialized data could be\n  disclosed (CVE-2019-18197).\n","modified":"2026-02-04T02:24:09.013998Z","published":"2019-11-02T16:54:34Z","related":["CVE-2019-13117","CVE-2019-13118","CVE-2019-18197"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2019-0313.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=25643"},{"type":"REPORT","url":"https://usn.ubuntu.com/4164-1/"}],"affected":[{"package":{"name":"libxslt","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/libxslt?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.1.33-2.1.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2019-0313.json"}}],"schema_version":"1.7.3","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
