Package : libonig
Version : 5.9.5-3.2+deb8u4
CVE ID : CVE-2019-19012 CVE-2019-19204 CVE-2019-19246
Debian Bug : 944959 945313
Several vulnerabilities were discovered in the Oniguruma regular
expressions library, notably used in PHP mbstring.
CVE-2019-19012
An integer overflow in the search_in_range function in regexec.c
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-2019-19204
In the function fetch_range_quantifier in regparse.c, PFETCH is
called without checking PEND. This leads to a heap-based buffer
over-read and lead to denial-of-service via a crafted regular
expression.
CVE-2019-19246
Heap-based buffer over-read in str_lower_case_match in regexec.c
can lead to denial-of-service via a crafted regular expression.
For Debian 8 "Jessie", these problems have been fixed in version
5.9.5-3.2+deb8u4.
We recommend that you upgrade your libonig packages.
