apache. Multiple issues were addressed by updating apache to version 2.4.53.

A flaw was found in ruby, where the date object was found to be vulnerable to a regular expression denial of service (ReDoS) during the parsing of dates. This flaw allows an attacker to hang a ruby application by providing a specially crafted date string. The highest threat to this vulnerability is system availability.

Privilege escalation can occur in the SUSE useradd.c code in useradd, as distributed in the SUSE shadow package through 4.2.1-27.9.1 for SUSE Linux Enterprise 12 (SLE-12) and through 4.5-5.39 for SUSE Linux Enterprise 15 (SLE-15). Non-existing intermediate directories are created with mode 0777 during user creation. Given that they are world-writable, local attackers might use this for privilege escalation and other unspecified attacks. NOTE: this would affect non-SUSE users who took useradd.c code from a 2014-04-02 upstream pull request; however, no non-SUSE distribution is known to be affected.

An issue was discovered in aubio 0.4.6. A SEGV signal can occur in aubiopitchsetunit in pitch/pitch.c, as demonstrated by aubionotes.

An issue was discovered in aubio 0.4.6. A buffer over-read can occur in newaubiopitchyinfft in pitch/pitchyinfft.c when the samplerate of the input file is larger than 50kHz.
