EulerOS Virtualization 3.0.2.2 : libcroco (EulerOS-SA-2020-1475)

high Nessus Plugin ID 135637

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the libcroco package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- ** DISPUTED ** 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_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_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)

- 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libcroco packages.
