Linux Distros Unpatched Vulnerability : CVE-2019-19012

critical Nessus Plugin ID 222775

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 leads to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (This only affects the 32-bit compiled version). Remote attackers can cause a denial-of-service or information disclosure, or possibly have unspecified other impact, via a crafted regular expression. (CVE-2019-19012)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
