Alpine: libcroco: security update to 0.6.12-r2

high Tenable Cloud Security Plugin ID 405143

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- The cr_input_new_from_uri function in cr-input.c in libcroco 0.6.11 and 0.6.12 allows remote attackers to
cause a denial of service (heap-based buffer over-read) via a crafted CSS file. (CVE-2017-7960)

- The cr_tknzr_parse_rgb function in cr-tknzr.c in libcroco 0.6.11 and 0.6.12 has an "outside the range of
representable values of type long" undefined behavior issue, which might allow remote attackers to cause a
denial of service (application crash) or possibly have unspecified other impact via a crafted CSS file.
NOTE: third-party analysis reports "This is not a security issue in my view. The conversion surely is
truncating the double into a long value, but there is no impact as the value is one of the RGB components.
(CVE-2017-7961)

- The cr_tknzr_parse_comment function in cr-tknzr.c in libcroco 0.6.12 allows remote attackers to cause a
denial of service (memory allocation error) via a crafted CSS file. (CVE-2017-8834)

- The cr_parser_parse_selector_core function in cr-parser.c in libcroco 0.6.12 allows remote attackers to
cause a denial of service (infinite loop and CPU consumption) via a crafted CSS file. (CVE-2017-8871)
