Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2649-1 advisory.

- An out-of-bounds read was discovered in PCRE before 10.34 when the pattern \X is JIT compiled and used to match specially crafted subjects in non-UTF mode. Applications that use PCRE to parse untrusted input may be vulnerable to this flaw, which would allow an attacker to crash the application. The flaw occurs in do_extuni_no_utf in pcre2_jit_compile.c. (CVE-2019-20454)

- An out-of-bounds read vulnerability was discovered in the PCRE2 library in the get_recurse_data_length() function of the pcre2_jit_compile.c file. This issue affects recursions in JIT-compiled regular expressions caused by duplicate data transfers. (CVE-2022-1587)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
