Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Information disclosure
EUVDB-ID: #VU18965
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-13117
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to information disclosure in numbers.c in libxslt library where an xsl:number with certain format strings could lead to a uninitialized read in xsltNumberFormatInsertNumbers. A remote attacker can gain knowledge whether a byte on the stack contains the characters A, a, I, i, or 0, or any other character.
MitigationUpdate the affected packages.
Opensuse: 15.1

No. We are not aware of malware exploiting this vulnerability.
2) Information disclosure
EUVDB-ID: #VU18966
Risk: Low
CVSSv3.1: 4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-13118
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to uninitialized stack data exposure in numbers.c in libxslt library when processing an invalid character/length combination in xsltNumberFormatDecimal. A remote attacker can gain pass specially crafted data to the application using the affected library and gain access to sensitive information.
MitigationUpdate the affected packages.
Opensuse: 15.1

3) Buffer overflow
EUVDB-ID: #VU21942
Risk: High
CVSSv3.1: 8.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-18197
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the xsltCopyText() function in transform.c in libxslt. A remote attacker can create a specially crafted XML document, pass it to the affected application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.
