Security Bulletin

This security bulletin contains information about 10 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU31219

Risk: Medium

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2018-16323

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

ReadXBMImage in coders/xbm.c in ImageMagick before 7.0.8-9 leaves data uninitialized when processing an XBM file that has a negative pixel value. If the affected code is used as a library loaded into a process that includes sensitive information, that information sometimes can be leaked via the image data.

Mitigation

Update the affected packages.
